I haven't used Mach4 for over a year and getting back into it. I wasn't fluent then and I'm still new so I make dumb mistakes which you may feel free to point out. This well might be one. 
I am simply trying to edit the startup script - which I have done before - but this time when I open the screen, select the Screen Load Script, the file that opens  one that opens is in the windows temp folder with a temp name  (C:\Users\Michael\AppData\Local\Temp\le267B.mcs) and when I save it, that's right where it puts it. But when I reopen the same Screen Load Script, my changes aren't there.
 
I have seen several example vids and they don't have this problem. They save and it just works. I did update to the latest version recently (4322 ?) 
What am I doing wrong?
