Almost every time I exit Stella (with Esc key), mGalaxy crashes. I'm not sure, but it may have to do with duration--if I enter a ROM then quickly leave, mGalaxy seems ok, but if I play for any more than a few minutes, mGalaxy will crash when I come back to it.
All other emulators work fine. I'm running the latest Stella 3.9.3 and mGalaxy 5.2 on Windows 8.1 Enterprise, 64-bit. I've attached log files if it's any help. .NET throws an error and then mGalaxy follows.
