Using Mach3 yesterday after a pause for lunch I found that I had lost the ability to move the mill spindle using the arrow keys on the keyboard. I had been using it earlier in the session without problems.
 I tried a different keyboard still no movement?. The spindle moves correctly using the MDI screen and when running a program.
 I normally use the keyboard to zero the Z axis and its loss makes things difficult.
Anyone able to help?

Have you accidentally clicked the Jog ON/OFF button ?

System now corrected and ready to go.
