[Qt-interest] QMenu does not respond to mouse click

[Matthias Pospiech]

We have a rather simple application which has two menu entries:
(File) (Configuration)

The menu is only accessible with the mouse over  the 'n' of 'Configuration'.

I deactivated all signal/slots and removed everything from the 
constructor, such that only the ui
is loaded, still the problem occurs.

Any ideas?
Compiler is mingw and Qt 4.7.3
