Update:
We believe we've solved the problem of the windows constantly popping up when hitting the "s" key. It appears that the Numerical Enter key was stuck in the down position and so we first unplugged it from the pc and then popped that key up and off and found that the metal clip under it was not on correctly, so we put it back in right and cleaned out from under it. We popped it back on and then replugged it in. We followed the directions for uninstalling the keyboard and then reinstalling so that the driver would update when we did it and now it appears that everything is working normally.

As to the Wild Tangent error, we reinstalled Wild Tangent and then did a complete Uninstall to rid ourselves of that particular problem. Thanks ya'll for all the help. We're planning on replaceing the almost 4 year old keyboard next week when SSD comes in. She's had problems with it since we got it, but this just has made us more certian that we're ready to replace it. She doesn't use half the keys on it anyway.

I know that if we have any more problems I can always come back here and some great people will continue to help us until we can solve the problem. Thanks everyone for suggestions and all. One great thing about this Midaddle/Stuck key is that we now have her computer extremely protected with AdAwareSE, Spybot/TeaTimer, Zonelabs and Spyblaster, amoung the few. I've wanted her to get them before, but this situation impressed upon her just why. Thanks for helping us.
