Cursor problems

When I make a runtime (.exe) file in Blender Publisher, the cursor doesn’t dissapear when I start the game. My cursor is in the way all the time!
My game is a first person shoot em up, where the cursor is in the center all the time.

Is there a way to hide the cursor? It’s allright when I play the game inside of Blender, but not in in the .exe file.
