Thanks for the replies guys,
problem seemed to be with the buttons being bound to the Alt/Cntrl keys (default), my computer doesnt seem to like it.
Changed the top buttons to B,N,M and it functions fine theres no delay at all, it was like the Alt, Cntrl keys were staying pressed and not comming unpressed till i pressed them again, i checked all this in Winpac.
Cant seem to get my shifted keys to function now though?
