I am setting up my lathe to run under Mach 4 Lathe and I am having problems entering the position into the X position readout box. I click on the Z value and it highlights and I can type in the position I want but when I do the exact same thing to the X position it does not let me enter a position. I have tried it with the system enabled/disabled, restarted my PC and Mach 4 several times and nothing, X is still uneditable while Z is OK to edit. I do this all the time in Mach Mill interface and thought that the Lathe interface should work the same, at least these fundamental basics.
If anyone could shed some light on this issue I would appreciate it.

Thanks
Scott

Systems setup:
Win 10 64 bit
Mach 4 Hobby version: 4.2.0.4300 (lastest I believe)
