QMdiSubWindow closes main window

[frido]

On one comp. I have qt 4.3.3. installed, on other (Suse 11) qt 4.4.0-12.2.

On first comp. my mdi app. works great, but on other when I close sub window this window automaticly closes main window.

Is this a bug in new qt or has been something changed.

Can you post some code?

If main window close suddenly, maybe it's a bug in your code, lost pointers..
