--- Comment #3 from VittGam winebugzilla@vittgam.net 2010-10-26 16:04:31 CDT --- Yes. You can't minimize Procaster main window or the toolbar, because the minimize command seems to use the LWA_COLORKEY to clear the window. So the result is an unresponsive always-on-top window. And the border clips are buggy too, because there is no transparency.
When I'll be on the computer with Procaster I'll attach the console output.
