After I started jEdit the first time it appeared to have hung. All windows were blank - but then I noticed that my hard disk activity led was flsahing - Java seems to be very slow on my computer.

Nothing (much) wrong with that, but then I went and changed jEdit Appearance to something else than the default (can't remember what), did a restart of the program as instructed, but now all other windows remain blank (a sort of a light gray color) no matter how long I wait.

I suspect this is because of the Appearance. Where can I cahnge it back, since the Global Options dialog isn't showing correctly either?
