You aren't the only one with this problem: http://www.sevenforums.com/general-d...solitaire.html
There are a bunch of other similar threads. As far as fixing it, I'm not sure. Life sure sounds rough, Okie, if this is one of your problems!
ETA: there is a workaround for it, but it sounds like you have to disable windows aero. People are saying this is causing reboot issues, as well as stopping the install of other applications. Pretty much a bug that doesn't have a patch yet.
