Hey guys, I think I stumbled onto a bug. After updating to MAME 182 and utilizing PortAudio in MAME using the WASAPI RetroFE will hang indefinitely and crash when trying to exit RetroFE. There are no issues with the emulator or RetroFE regarding sound, that all works fine. When I go to exit RetroFE it hangs on a black screen (5+min) and if I press Escape it will crash.
Using another API for PortAudio or disabling PortAudio in MAME allows RetroFE to close normally. I checked the log and there doesn't seem to be any errors, the last line written is "[SDL] DeInitializing" which is where it hangs, RetroFE never exits. This occurs on the 0.7.20b3 build and the 0.7.20b4 build posted today.
