OK, I'm back. According to the logs BFG client is trying to stop windows desktop manager and of course windows doesn't like anybody stopping them from doing anything (power issue, probably Ego, Freud would say). I tried some things I won't suggest to others because I don't want them to mess up thier box. Here's what works, un-sanctioned but effective. Go to C:\program files\chessmaster challenge\<find the exe file (it'll be the game icon)>, right click on it and find and hightlight 'run as administrator' on the the pull down menu. You're in, now you can decide if you like it well enough to do that everytime you play or contact CS. I'm going to give it a shot and if I like it I will try further steps to contact CS with my findings. They are really good to work with and do try 'make it right' when they are made aware. I hope this works for anybody that comes back to check the post, happy gaming.....
