I think I may have fixed my problem, so for any of you who are experiencing the same thing, try this: Go to your graphics card options, and make sure you have Anti-aliasing turned to Application Controlled. Dont have it manually set to whatever you like, as when I set this back down, I havent been kicked to desktop since. I have actually been able to stay on for hours on end now, so I am assuming that the problem is fixed. So give it a shot, and see how it works out for ya.
