I will try to test that at work today. I am using vtk-5.6.1 and
Qt-4.7.3 on windows xp64 and windows 7 64 bit. I have never seen this
effect however I never mess with the scene with a QMenu open. I
definitely have manipulated the scene with QWidgets open but these
dock to the right of the QVtkWidgets in my application and reduce
their size.
