FPS drop, mouse issues after adding a few key maps...

I love this program and it worked really well from the start. Until I added quite a few key maps...my active window started to have this mouse issue where when I looked to the side, it would "snap" to looking at the ground. Obviously, not playable. I switched out mice to eliminate that problem, ran some virus scans thinking it might be something odd there, nothing showed up. I just ran 3 instances out of the same directory and EQ is smooth as usual. My box can handle running 4 [quad core, ati 5870, 12gb ram all on water].

Lax, any ideas?? Also, the framerate of my inactive windows went from being fluid, to 1 fps!

Something is up!
