Cannot drop widgets in Qt Designer 4.4.0

Hi,

Using Qt Designer 4.4.0 I can only drop widgets onto a dialog the first time Designer is open. Subsequent times I am unable to drop a widget (I see the no dropping icon) and the top level menu with "File Edit etc." disappears from view when I drag the dialog around.

In addition when the top level menu disappears it is replaced by a grid of small dots and sometimes I see a copy of parts of the dialog I am editing in place of the menu. Weird.

After rebooting Designer can again drop widgets only the first time it is open.

Has anyone seen this problem? I compiled Qt 4.4 Open Source Edition with mingw under Windows XP.

Do you have any custom WinXP themes installed?
As far as I remember this was a problem in previous version of Qt.... most likely it exists now too.

Try uninstalling any custom themes you may have.

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)?
