We recently had to move from Windows 7 to Windows 10 for one of our machines. I saved the mach4 directory from the Windows 7 computer, copied it to the reformatted computer, and then installed 4.2.0.4517 over the top of it (as recommended here:
http://support.machsupport.com/en/kb/articles/updating-mach4)
Everything was fine except that whenever I tried to open the screen editor to edit a screen that had been part of the old installation (a custom screen) it would crash Mach4. Editing standard screens that were part of the 4.2.0.4517 installation was not a problem.
I did the same thing with 4.2.0.4470 and everything worked fine so we are currently running 4.2.0.4470 on that machine.
I am worried that I will have the same problem again if we ever need to upgrade Mach4 beyond 4.2.0.4470. Does anyone have any ideas what might be happening?
The old version was 4.2.0.4300.
Thanks!
