For what it is worth, I have also noticed similar issues with the Qt  
4.5 cocoa build- in my case, though, it was that the menu items  
weren't being disabled, even though I explicitly asked for them to be.  
The same code compiled against a non-cocoa (i.e. carbon) build of 4.5  
worked fine. I posted about this here a while ago (as well as some  
window positioning issues I was experiencing only in the coca build)  
under the subject "Qt 4.5.0 cocoa build issues", but no one responded.  
I wouldn't be surprised if your issues were simply another  
manifestation of the same problem. And no, I haven't figured out any  
work-arounds, sorry :)
