Brian;

I looked into it and Vista can only host the 2007 version. I installed it and loaded XP into it but found it can only see the virtual disk it's installed on while I need it to see the E:\ drive on the real hardware.

I could do a dual boot installation but that would mean rebooting every time I needed a DOS program. Not efficient as I switch back and forth frequently.

My DOS shell program will run under Vista, I just can't get it to do full screen and the TB program is only about half height. Possible but not comfortable.
