HI,
The only purpose of this application is to show a first dialog, where you can open a 2nd one, then close that and the first one.
But when I call DestroyWindow() (= close) on the 2nd dialog, it closes it, minimizes the other one and completely freezes the whole application. I can re-maximize the 1st dialog, but when I click anywhere it just makes "bing".
Again (what happens):
- open dialog 1
- open dialog 2
- close dialog 2
- gets closed, dialog 1 gets minimized
- i can remaximize it, but the whole thing is frozen (just "bing"-sounds)
It's a very small project, I'd really appreciate it if someone could have a look and tell me wtf could be wrong.
