When the Unravel program is run in applet program mode, some operational restrictions apply. The program is run in the "sandbox" environment and is not stored for later use on the user's computer. Furthermore, writing to the user's hard disk by the Unravel applet program is not permitted. However, users can copy text information presented by the Unravel program to files they create, external to the Unravel program, on their hard disk or other storage medium if they desire. Because of the writing limitation for the applet, it is recommended that the applet mode be applied by users only:
to assess initially whether they wish to download the application to their computer (by other means), or
for unscrambling cubes of small size (that can be unscrambled during one session with intermediate storage of cube state not required).
The applet problems, referred to above, don't arise when the program is run as an application (refer to UnraveJ WebStart and UnravelJ Direct options). Differences in applet and application program operation are expanded upon in the relevant help topics.
Due to security issues some browsers do not support applet viewing.
