When I attempt to open any .set file with Screen4, I get as far as choosing a resolution. Immediately after I choose a resolution (any) a small box appears with a yellow triangle symbol with an exclamation point in it. Just below that is an OK button. No matter where I click after that, nothing happens. Only way to close the program is through ctl-alt-del. This is on three different computers, one of which is my Mach3 control box. I can open the .set file with the old screen designer. I have re-downloaded Screen4 in case of a corrupted file.
Any suggestions would be greatly appreciated.
