I ran into this thread while I was waiting for someone to reply again to my thread on One Monitor and Two Computers and I tried changing the User Account Control in the Control Panel and it worked. When I changed to Windows 7 64-Bit and used Turbo Cad v12.5, I would always need to reset the desktop the way I wanted it to look. Now, the only adjustment I need to make is to make Large Icons in Tools/Customize/Options/Other.
It frustrated me to the point that I wanted my old computer back and I was looking at KVM switches on eBay. I even began shopping on eBay for another Turbo Cad version. I looked at v18 Pro, v19 Pro and v19 Pro-Platinum. I would have gone with a version 19 to get the most out of 64-Bit but now things might work out OK for a while longer. I like TCv12.5 and it does what I need and the best part is I saved $300-$400. Maybe someday I'll step up to a newer version if I hit another snag. I'd like to find out what a lowered User Account Control will do to the rest of my computer workings.
Thanks a bunch,
