I loaded a PNG file into a clip and activated it on a layer, Within seconds Arena crashed. I sent a crash report.
99KB PNG with alpha, 1109x1024 pixels. 1920x1080 composition.
Now Arena crashes / freezes when starting up.
Worse than that, I now have a "Resolume Arena (Not Responding)" window occupying my desktop that has survived beyond closing the program - I can't do anything to it now, and there is no Resolume process in Task Manager. Boo!
Windows 10 Pro x64.
