Did you find out?

Every time I click on the drop-down box "Combo Box", I start a thread.

Please check this video, the official original file also has a bug

Please start the program, reproduce the bug, and while the combo is doing whatever it isn't supposed to do click "pause" in the debugger. Then extract the stack trace(s) and upload them for us to inspect. It's impossible to tell what's going on without any information about what's being executed (i.e. no source, no stack).

Every time I click on the drop-down box "Combo Box", I start a thread.

Why do you do that?

PS

Ah okay, I understand now what the problem is. I have no idea why you get that. My advice is to try it as follows:

1. The precompiled packages that come from Qt Company
2. In a clean virtual machine. Also one that's not localized.
3. Finally if 1 and 2 fail, try with a localized virtual machine

If it's present in case 1, 2 or 3, then I'd suggest filing a bug report on the tracker.
