I will wait.
I cannot find any other solution instead of using the static global QMenuBar instance on Mac. The attached patch does: * enable the About and Preferences dialog application wide on Mac * use static global QMenuBar instead of view related instance on Mac * do the Mac specific menu bar init only the first time All changes are inside #ifdef Q_WS_MACX blocks. This works for me and nothing else. One drawback I can see: the About and Preferences dialog don't show up if there is no view. Stephan
