Keep popping out of window

[Stoggieman]

I have tried playing in full screen and I keep getting booted out of the window. I don't quite understand what's going on here. When I play in windowed mode, I'll also have the window go as the non selected window, making my toon keep running, turning, etc. Any advice on this? This could wipe groups etc later, right now it only hurts me. But still is incredibly frustrating.
