[Help] Keys sticking/Lagging.

Since the patch 3.03 ive being having problems where when holding the right click to look round on my main and using direction keys at the same time the direction keys seem to stick.
I am currently in window mode and using keyclone. it seems to do this when i first load up after a reset, the past few days ive being able to fix it with lots of fiddling until the next restart. but now it doesn't seem want to stop.
To fix it before i fiddling with hardware mouse, graphics, resolution settings and restared keyclone. i dunno which fixed it. if anyone has had this problem i would be thank ful to help get rid of this problem.
