I have just moved my touch screen into the workshop and linked it up to Mach 3 - it's great.
I was altering some of the screens - basically to give bigger buttons for my numb fingers, and add jog buttons to the basic set and lset screens. I had a niggling thing happen - when I made an alteration to an icon, say an OEM code, or a picture size, when I pressed OK, the image jumped, usually about 2.5 inches to the left, sometimes, down the screen, and I had to search for it, then bring it back to it's correct position.
What am I doing wrong, or not doing
