weird movement

[corrie]

Hey all here is my ? On initial start up of my computer I startup Mach3 and as usuall hit the reset.Turn on my controller then back to the P.C. When I jog any one axes while holding the shift key to speed it up ,like lets say the Zaxes I end up getting another axes moving at the same time. When I stop jogging and pause and change axes jog the problem goes away. I have absolutely no other programs running in the background while in Mach mode.Would this call for a stand alone P.Pcard instead of using the onboard P.P. ? This problem has just showed up and have not seen this before on my system,thanks.
