When I leave my cursor alone for 10 seconds, it randomely dissapears.. What the hell? When I move it or click, it's fine for another 10 seconds.. :?

This is actually normal , sort of

 

 

 

 

 

 

 

Windows Media Player introduced this feature when playing video, if you are watching a movie and dont move your mouse , the cursor disappears so it doesn't get in the view of the video . Alot of mouse drivers also implemented this feature as an option and WindowsXP itself has the option to hide the cursor when typing.

 

 

 

 

 

 

 

Check out the settings in Control Panel > Mouse

 

 

 

 

 

 

 

you may find that feature is selected somewhere :)
