These were the drivers I used on both machines
I'm perfectly fine telling her she has to get on the floor and unplug both computers VGA and USB, wait for 5 seconds, then plug one back in first, then the other... she just don't really want to do that everytime she boots the computers.
The replaced switch ended up working better than the older one, both the same model. However half the time the keyboard does not switch to the windows 7 pc, but re-switching solves this. I'm just going to say it was a broken unit and the rest is not having fully compatible drivers. I couldn't find anything for a KVM that works with 64bit fully with no problems.
ConnectPRO new UR-12+ or UR-14+ models with USB DDM technology which provide true USB device mapping to each connected systems. This USB DDM patented technology is the only solution for sharing among Windows 7 systems.
