bad effects of mouse movement

whenever i move the mouse within my rendering window, windowed or fullscreen, i noticed my fps starts shooting out incorrect numbers. like 30,000 fps when i have vsync on at 85 hertz. however when i dont mouse the mouse everything is fine.

could this have to do with windows messageing, because its processing a mouse movement message and messing up my fps code?

i know my fps code is right, so its got to be something else. any info is appreciated, thanks
