[gaim-migrate @ 1446]
this didn't bother me until *SOMEONE* pointed it out ;). and benjamin, if you read the gaim cvs logs, no, i haven't figured out what Qt's problem is, and I run at 75 dpi, not 100. but I bet kaim would look quite a bit different if you developed on my machine ;) Anyway, now close.xpm is only used once, and not for closing, despite the name.
