      Hi,

      I have some problems since changing from windows xp to windows 7.

      By click or moving the mouseptr over a button i received following msg:
      QWidget::repaint: Recursive repaint detected

      with closing of the host program (http://www.hermannseib.com/vsthost.htm) i received following msg:
      QPaintDevice: Cannot destroy paint device that is being painted
      QThreadStorage: Thread 0x2238840 exited after QThreadStorage 2 destroyed

      Also it seems that the focus is sometimes lost.

      Starting with the debugger it throws a Segmentation fault.

      Here is the code with QtCreator Project (new project template, minimal implementation):

        Findings after a year.

        !! Do not try to make a VST Editor with Qt GUI !!

        You will inevitably encounter some problems.
        Handle qApp instance, manage 2 or more plugin instances, .....

        Of course you can use the Qt lib if you don't need SIGNAL/SLOT stuff.

        Separate the Editor in a new Process and communicate over RPC between plugin and editor.
