Complex menus are more difficult to operate in Qt4 than they were in Qt3.

Qt tries to integrate with the platform and follow platform guidelines so I was suggesting this is an expected change. Try running your application with a different widget style (like "Plastique") and see if it changes anything. If it does then you can modify the behaviour of your application by subclassing the style and returning some different data in a proper place. If not then without digging deeper it will probably not be possible.
