On XP or 7?

These changes are not yet fixed.  At least here the selected frame
remains topmost even after the dialog finished which is even worse
than the disease it tried to cure.  I have to remove the frame from
that group, probably in w32_dialog_in_progress.

Please install without any remedies.  If I find a way to fix this I'll
get back to you.
