I use one of the keys for walking (W) in the game I play. At 1st it responded perfectly but after a few weeks it doesn't respond all the time. I'm constantly having to press let go, press let go. I then switched my walk to a different key and the same thing after a few weeks. I only have use of my left hand and it is very limited so I can't use the joystick for my direction movement. Please any help would be appreciated. This is my 2nd Cyro and it did the same thing on the 1st one.
