I’m using SDL for mouse input to control the view of the player in a 3D  
environment. I’ve hidden the mouse cursor but now the problem is that when I  
move the mouse to much downward then my windows bar appears and the SDL  
window looses focus and doesn’t respond to mouse input. Only when I mouse  
the mouse back up again and press a mousebutton than I regain control.

What might also be important to mention is that this only happens on my  
laptop (touch-pad). I’ve tested my prog on a mini-tower and there this  
problem did not accur.

Any suggestions?

Grab the input with SDL\_WM\_GrabInput()

I already was using SDL\_WM\_GrabInput(); It doesn’t help.

Perhaps it’s because of the labtop/touchpad as I mentioned before. If anyone  
got any other ideas or suggestions, please help.

Well, is the laptop using standard Windows mouse drivers - and, most  
importantly, is the laptop using the latest version of DirectX, or at least  
the same version as on your other machine?
