Where are the tests you initially had in your patch? I assume you accidentially
resent an old version. The tests are still useful to make sure, that noone will
break this fix again.

Also, please review all the occurances of WM_CAPTURECHANGED, and fix them
accordingly. If the code doesn't look like it can handle the double
notification, then just ignore them based on the condition lParam == hWnd. This
could also be done in separate patches before.
