First, thank you for your wonderful work! It's a fantastic emulator, and it has replaced Vice on my Mac.
Unfortunately I've found a pretty annoying issue with keyboard controls. When I play a game like Commando, and I switch from "up and left" to "up and right", sometimes the "right" key isn't registered, so my soldier just keeps walking vertically (even if both the "up" and "right" keys are actually pressed). Happened to me with two different keyboards.
Also, when you switch from left to right without pausing, your character just stops - this is very noticeable in Impossible Mission and many other games.
Could this be fixed?
Thanks a lot!
