AM freezes when using trakball to scroll through games list

[VidEng2]

Running the latest AM on a core2 duo windows 7 32 bit machine with an Ipac4 and a Happ 3" trakball. I tried to set up the trakball to scroll through the games list but as soon as I move the ball, the entire app freezes. I can make it un-freeze by using the stick or keyboard to scroll though the list but as soon as the trakball is moved, it does it again.
