Working with Eclipse for nearly half a year has definitely messed with my shortcut-fu for DrJava. I keep pressing the wrong buttons now:
|Go to class under cursor||F3||F6|
|Go to class||Ctrl-Shift-T||Ctrl-Shift-G|
|Run unit tests||F11 / Ctrl-F11||Ctrl-Shift-T|
Very confusing indeed.
I decided to pick up working on this file I/O bug  in DrJava again, though, and I verified that the font dialog in Windows 7 is verifiable problematic .
