He is using Logitech wireless keyboard and mouse 310 Laser combo. I'm in process of upgrading his Logitech drivers, as it seems he still had old drivers that ay have been part of the problem. then I suspect it may be problem that Microsoft has with allowing the wireless drivers to override certain keys or whatever he found out from the site he linked.
I would suggest he also cross post this in the technical forum, since so far using his account the problem wasn't showing up there. I log on to see if I could find posts on issue using premium account features.
