Oracle has released Java 7. Java 7 contains a bug that stops FTP uploads of MyFTPUploader on Windows Vista 
and Windows 7. MyFTPUploader with FTPS (FTP + SSL) can still be used with Java 7. See for a description of 
the bug http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7077696. Please vote for this bug! The more votes 
the higher the chance is that Oracle will solve this problem sooner.

Due to the bug FTPS can only be used with Java 7 on Windows Vista and Windows 7. To enable FTPS see:

Please check if your FTP server supports FTPS.

Drag and drop doesn't work anymore on Mac OSX 10.6 (Snow Leopard) and OSX 10.7 (Lion) with the latest OSX 
updates. At least Safari 5.1, FireFox 5.0.1 and 6.0.2 and Chrome 13.0.782.112 and 14.0.835.186 with Java 1.6.0_026 
are infected. Not only the uploaders of JavaAtWork have this problem, uploaders of competitors have the same issue. 
It is unkown when Apple shall resolve this issue. As a workaround the copy-and-paste functionality can be used.
