[Qt-interest] Different behavious QWidget in 4.3 compared to 4.5

[Eirik Ulvik]

Hi,
I have just upgraded from Qt 4.3.3 to Qt 4.5.2. I had some code that 
opened a widget with the Qt::FramelessWindowHint and 
Qt::WindowFullScreen flags set. This widget was resized to the full 
screen by using QDesktop functionality. The widget itself had no parent. 
This worked perfectly before and shows a full screen overlay, but does 
not work anymore with the new Qt version. What basically happens is that 
all functionality "under" the overlay is gone, but I cannot see the 
overlay. Does anyone have an idea about what the problem might be?

Regards,
Eirik
