Two things were driving me nuts about Windows 7 and the Lenovo -- the USB Webcam won't work and I can't find the drivers. Also , I couldn't get iPrint to work.
SO, I backed up the Windows 7 install to the HMS, and put the XP back on. There are several issues on that OS bothering me, so I have fixing them. There is a file that wouldn't let me shut down the computer automatically, and a couple of other programs that automatically load that I have to shut down each time, or they are in the way (Lanschool and SmartBoard).
I've also fixed an Outlook issue.
All in all, it does make the experience much more pleasant!
