Describe the bug

When multiple windows of certain programs are open, and the user attempts to close them with the cross button above the taskbar thumbnail, DWM will crash.

To Reproduce

Steps to reproduce the behavior:

Specifically, this happens most often for me with IDA. If I have multiple IDA windows open (with changes made to the IDB), and attempt to close one of them in this way, DWM will crash every time.
