When I purchased the 3040 Chinese CNC mill, I had 3 choices of operating systems to run the machine, XP, WIN 7, and win 2000. I like the XP operating system so that's what I chose.
To be honest I have never seen a dialog box like that.
I did find it though, nothing is adjusted from factory settings.
I found the issue with the Squares. My error, my squares were not squares, I had hit a node tab and altered it. After redrawing the square the issue was resolved.
Moving forward through positive action.
