Hmm.. That's weird, but then again I've seen Win98/ME do stranger 
things. Try calling SDL_WM_GrabInput(SDL_GRAB_ON) after you init 
everything, if you don't do it already. If that doesn't help, try hiding 
the cursor when the app gains mouse focus (on SDL_APPMOUSEFOCUS instead 
of SDL_APPINPUTFOCUS) or just check against SDL_APPACTIVE when you get 
an SDL_ACTIVEEVENT. That's pretty much all I can think of other than 
checking every frame if the mouse is visible.
