I've used mach 3 for several years and the jog screen has always worked as expected. I moved my milling machine (taig) and computer to a different shop. Now when I turn it on I can't get the jog screen to show when I press "Tab". On the right side of the screen I can use my mouse and it will grab a line and I can drag it over, thinking this would bring the jog screen back, but I  can't get the jog back at all. I have restarted but no help.
Any ideas what I can do?
Thanks

when I set this up I changed the keyboard because the old one was dirty. the new keyboard is a USB. well I put the old keyboard back on and now it works. the old keyboard has a round plug. Maybe If i reinstall with new keyboard it would work?
Note, the new keyboard would jog with the direction arrows and PU and PD,

Defective Tab key on your new keyboard perhaps ?

Tweakie.
