When holding down a key for longer period it gets "stuck" down for a moment and it gets worse longer it is held down. For that moment input from keyboard gets "frozen" and it is not accepting any new input.

This started happening yesterday with throttle, the worst is that the effect of getting stuck is proportional to the time the key was being pressed, for instance at the end of the main straight on Blackwood it gets "stuck" much more time than in any other part of the circuit.

Please help me!
