BugFixes (youngest to oldest):
=========================================================================
(Note: dates in day/month/year)

29/1/11 Fixed bug introduced on 1/1/11 that was preventing .gpx files from being opened
1/1/11  Changed variables to increase the no of data beyond 33766. (Now limited by memory) 
	Added 3 more User Girdles to Girdle panel.
        Changed Preferences dialog to handle the new girdles and fixed bug that was not changing new 
	girdle styles in the plots.
        Revised About.. and start-up flash screen text. Fixed bug in Save routine that was not
 	allowing Cancels to be clean. Revamped compiled HTML Help and made it the default within GEOrient.
9/5/10	Enlarged orientation and information panels at the bottom of the screen to accommodate larger fonts; 
	Added new font control boxes in the Preferences dialog to manually change the fonts in these panels.

24/5/09 Fixed cramping of statistics box against the plotted rose in some forms of rose diagrams; 
	Fixed non-plotting of compass bearings if a simple axis setting was chosen in the Preferences. 
	Modified wording of rose diagram statistics to indicate basis for confidence calculation.
5/5/09	Added routines to process more efficiently grouped rose diagram data where the sector frequency is
       	embedded as appended numeric values. Included adding an extra option in the File Format dialog.
       	Revised the calculation of the circular median and fixed a bug giving incorrect circular variances,
	skewness, and kurtosis for certain types of data (axial data and pre-binned data).
       	Revised Advanced Stats to report the Circular StdDev in degrees (not radians)
       	Fixed cramping in copyrite form; fixed cramped Raw values given in Classification module.
       	Corrected bug in Number-of-data caption for classified plots; Fixed problem accessing Appended name 
	combo in File Format dialog
30/3/09	Fixed cramped option buttons and labels in Classification dialog and Rose dialog. Fixed bug causing Classification legends to
       	be plotted incorrectly as %ages. Modified lables in Classification legend

	plotting incorrectly as %ages.
24/2/09 Fixed bug causing rose plot legends printing double
5/6/08  Fixed bug causing crash in Rose plots if only one data point
14/1/08 Ver 9.4.0. Added new Workspace option to save and open multiple plot layouts.
        Added options to plot either means or cumulative values in the stereo classification routine
        for appended data. Added new sorting options to the rose classification dialog.
        Corrected slight bug in plotting grid density plots where points were not being plotted
        in the last grid line. Added new items to the binary .gpx Save routine to save the various
        classified plot options. Added new stats about the appended data to the stats box.
4/1/08	Corrected anomalies with the plotting of calculated girdles with dips >87 degrees.
	Set fabric and legend boxes to be open by default. Corrected bug in stereo classification routine 
	for data containing missing Appended values.
28/1/07 Allowed alphabetic sorting of classified alphanumeric data. Set opening directory to default to
        the Last-Used directory. Included legends on P & T plots.
9/11/06 Released ver 9.3. Added options for classified plots that allow the orientatons of appended numeric data
        to be contoured by the mean value of the numeric data in addition to the orientation of the data.
	This option added by request to handle petrophysical acoustic measurements, but
	probably would be quite useful analysing 3D directional numerical parameters such as 
	ore body thickness or tenor; vein widths, etc
1/11/06 Fixed bug preventing Class 9 numeric values to be changed in classified plots
13/1006  Corrected problem with Terzahghi Correction not being applied to simple Frequency-Azimuth roses.
17/4/06  Corrected problem in rotation menu not rotating overlaid Secondary data.
        Corrected minor problem with canceling smootly out of File Format dialog.
16/12/05 Fixed bug in line rotation procedure related to rounding errors that produced opposite
        quadrant line sense for some zero plunges (very minor problem, unless 
	unfolding polar lines to horizontal).
        Fixed bug causing 95% confidence arc in rose diagrams to be only partially drawn
        for means close to north. Changed Advanced Stats to not round azimuths to integer values		                
	Corrected Advanced stats Box to include Simple stats when manual girdles showing.

18/7/05 Cleaned up some control references and recompiled using an upgraded MSCOMCTL.OCX
	to fix some reports of installation problems. No change to program functionality.
4/7/05  Fixed bug preventing rose diagram scales to be manually set.

22/6/03  Released Version 9.2. Fixed problem of rose plots showing partial quadrants giving 
	variable statistics. Fixed errors in some stats routines for some measures of 
	dispersion of axial data. Added calculation of circular median to rose stats, 
	and corrected Mean Deviation calculation to be around the median. 
	Replaced old 'Mean Deviation' arc with arc showning 95% Confidence Interval on 
	Mean Direction. Changed rose diagram stats box to reflect changes. 
	Fixed bug causing some Convention settings not to be saved correctly. 
	Enhanced Save options in the File Format dialog so that a full, predefined, 
	column configuration can be saved and reselected.
             Fixed bug causing crash on opening some "empty" rose diagrams.
	Fixed rounding error bug causing some vertical girdles not to plot.
9/3/03   	Modified contour and grid plot procedures slightly to minimise grid-fill anomalies 
	in certain plot configurations, and to minimise contouring problems in plots 
	in which single points translate to integer %age density values 
	(e.g. plots with 50,25,20,10,5, or 2 pts).
15/1/03	Fixed new bug in Registration module preventing correct registration
30/11/02  Fixed bug causing points not to be displayed in .gpx plots having more 
	than one overlay datasets. Fixed crash when clicking within displayed 
	data spreadsheet grid. Slight changes to Registration module.
19/5/02	Released Version 9.1. Corrected Error trap routine for opening some 
	.gpx files. Corrected bug that caused legend, fabric, stats toggles 
	not to work with printing, and some displays. Saves toggle info in 
	.gpx files - hence new version no. Improved elements of the printing 
	dialog graphical interface. Fixed several minor annoyances.

6/12/01  	Released Version 9.0. Changes introduced in version 9: 
	Added new plot stereographic routine for intersection lines between primary
	and secondary planes. Added new data classification options to both 
	stereographic projection plots and rose diagrams. Changed the input 
	formatting options to the Appended data to accommodate the classification
	options. Added routines to copy legends and Statistics boxes to clipboard.
	Cleaned up some menu shortcut anomalies.  Increased number of plot window
	limitation for unregistered users so that all the kinematic axes routines
	can be used by those users.  Added new rose diagram plot and display 
	options: Classified roses, wind roses, overlayed wind roses. Changed many 
	Preference Options for rose diagrams, including introducing new displayed 
	scale and sector options. Corrected bug in Rose-Length and Rose-Length 
	variance plots; Corrected bug in saving and retrieving some .gpx files. 
	Corrected many obscure minor bugs causing inconvenience or occasional 
	crashes. Corrected problems with European Windows settings using 
	comma decimal delimiter. GEOrient now decimal Locale aware. See the 
	section on International Considerations in the Help contents.
13/9/01 Fixed bug that caused incorrect symbols to be plotted for points in the base 
	dataset of a multifile plot when the Overlay or Merge datafile contained
 	non-data lines.
25/3/01 Fixed bug that caused crash when copying data input originally in 
	strike/dip formats.
8/1/01 Fixed bug in calculation of kinematic P&T axes in which some data were 
	plotted with reversed axes. 
30/9/00 Fixed bug in accepting data input files in which some non-used input 
	values are null.
2/9/2000 Fixed minor bug that caused new Plane data added to a blank plot via the 
	manual data grid to be entered as poles rather than as dips.
17/8/2000 Fixed bug that caused .gpx files to crash if they contained plot windows 
	that were either maximized or minimized.
