That's worth checking. I'm pretty sure they're running the proper exe since the shortcut didn't change after the upgrade, and they do seem to have the upgraded stuff, but I'll make sure.

>Another thought... might the user be employing some other software - perhaps to do with disabilites - that interferes with the screen function?

I don't know offhand what is running. Certainly no disabilities software, but I'll have to check what else might be there.
