4 months ago This also happens when saving because when you are forced into a new window (like alt-tabbing or saving an unsaved build with ctrl + s) the program thinks that those keys are still pressed. The easiest way to fix this client side is just as you have said: repressing the key as to register it is no longer being pressed.
Whenever alt-tabing into protobot, the duplication mode will be toggled on until you press alt again. This issue doesn't happen if you rebind duplication.
