[Qt-interest] Menu Bar on Cocoa becomes disabled with Qt 4.5

[Mike Jackson]

I have an application that I compiled against Qt 4.5 built with Cocoa. 
The issue that I am seeing is that when my Application uses its menu to 
open a file (standard File->Open) using the standard Qt file dialogs 
and after the method has returned and my file is opened in my 
application all the menus are now disabled (grayed out). If I click to 
another application (any other one) and then click back on my 
application to activate it then the menus return to the normal state 
again.

  Anyone have any ideas what the problems might be? Same code compiled 
against Qt 4.4.3 (Carbon) works just fine.

 Thanks for any pointers.
