What is bit depth? :-) can you tell from that? That is interesting.
At 16 bpp, the symptoms I reported don't occur, and all is well. I
guess you suspected that, but it didn't occur to me to check before. I
might be the only wine user who habitually uses 8bpp: I can't see any
difference between 8 and 16 bpp. Well, with your patch in I can.

I'll get on with some more tests now, but I want to give you that to
start with.

Dammit, my winelib sendmail program won't work unless X is running. Try
