[PyQt] qt designer bug in both pyqt4 and pyqt5 for windows

I've done a lot of work on pyqt5-tools recently... but just found yesterday that my testing was apparently woefully incomplete.  It does work some places, but not in my fresh VM.  I'll have to dig a bit and see what I've got wrong.  Sorry for the trouble.

Cheers,
