[Qt-interest] Saving/restoring window position does not work in KDE 4 (but works in KDE 3.5.x)

[Marcelo Magno T. Sales]

Just adding some information...

I've just noticed that the problem is not related to KDE 3.5.x or 4.1.3. 
The position is not restored correctly when the user terminates the 
application clicking in the exit button in the title bar. When the user 
ends the application using the menus or the toolbar, the position is 
restored correctly (QApp::quit() is triggered in this case).
How can I work around this?

Thanks,

Marcelo
