After serious problems with 4.3pre2 (keyboard froze all the time), I upgraded my openSuSE 10.1 notebook to pre4. The keyboard doesn't seem to freeze anymore, but now the text area content has become invisible. I tried to change all sorts of Global options, but to no avail.

This repeatedly occurs in the activity log:

Any advice?

(And: would it be possible to increase the width of the forum dropdown list on the submission page? On Linux Firefox 1.5.0.1, I can see only the introducing dash and the first two letters of a forum's name, which makes forum selection pure guesswork.)

Thanks in advance,
