I installed a fresh copy of Mach 4 (Mach4Hobby_Installer-4.2.0.4162.exe) I immediately went into the screen editor. I didn't make any changes, and when I exited I got a popup titled "Unload Script Error" with a message that says "Correct the script error and restart." This happens every time I exit the screen editor.
I haven't the faintest idea on where to start looking for the issue. Anyone have any ideas?
