Buffing mule

hey guys. I want to know how to control two mapleroyals windows at once! I know its possible because ive done it before on accident, lol

 

Someone should correct me if I'm wrong but I believe that "dual input" happening only affects moving (arrow keys) and jumping.
It happens when you focus more than one maple window, which happens on accident quite often for me too

 

I hope that's not how this works

Here you can read about someone who asked how he can prevent it from happening.

Think about this, if multiple clients could take keyboard input, this could be abused. Robotic play should not be encouraged.
