Hmm... I just use the Windows XP theme with a few modifications to it (custom background, smaller title bar and minimize/maximize/close icons).

I reverted back to the default XP theme, started Designer several times without the problem happening. But now I went back to my modified theme and I can't reproduce it again. Argh...

I bet this problem doesn't occur under X Windows? Does it happen with the commercial version of Qt (I guess it is the same code)?
