Original Post
To check that i had SDL properly installed and everything, i made the little silly program below(it display a background picture and draws a smaller picture where the mouse is clicked, if a key is pressed it takes a screenshot and restores the background). It works fine windowed, but when i added the SDL_FULLSCREEN flag i ran into trouble, weird things happened when i clicked the mouse. Depending on the other flags, the background disappeared, or the small pictures moved(!) when i clicked the mouse, or just became transparent in the center...
Can anyone help me fix this, i would like to know if its because im using it wrong(likely) or because of something else beyond my control.
Here is the very simple code 
EDIT: Just wanted to add that im working in Windows XP with a Geforce 2 64MB card, could that be the cause?
