Hi
Any suggestions welcomed to sort me out on this please.
I am running Mach 3 Mill and suddenly my rapid traverse in continuous mode using shift on the keyboard and up/down or the  arrow keys on the keyboard has stopped working and just works in slow traverse mode. Its as if the Shift Key has not been depressed. It also doesn't work either when I use the arrow keys on the Control Buttons Flyout. I have tried another keyboard so I know it not a keyboard Shift Key problem.
G00 rapid traverse commands in all axis work fine at full speed.

Any thoughts?
Thanks
Tony
