Hi! I'm having a little issue with my emulator, and I was hoping I could get some help.

When I press F4 to fast forward, it does so, but I can't turn it off by pressing it again, and I need to reset the emulator to get normal framerate. Not only that, I can't navigate the GPU menus at all with DELETE, PG DN, etc, before or after turning on fast forward.

Is there a way I might be able to fix this? I don't recall having this problem a year or so ago, so maybe there's something I can adjust?
