[SDL] SDL_MOUSEMOTION event bug in Windows but not Linux

[Brian]

Mouse motion tends to generate lots of events. Your event queue is
probably full (SDL_PushEvent should return an error in this case).

Perhaps you should change your setup, seeing as you acknowledge that
it is bad =)

Adding a callback feature that calls various functions depending on
the event type would probably not be too difficult, depending on your
programs current structure.

If you need help can we take a look at your current input code?

HTH.
