Oops, I haven't read the original message, just Stephane's reply :)

If your mouse cursor is not within the SDL frame and you warp the mouse, you 
get an enter notify, not a motion notify.
Therefore, SDL does not update its internal mouse state.

What's about calling SDL_PrivateMouseMotion even when getting an EnterNotify?
