I launch the game and everything is fine.  I can see my cursor and all the menus are working, once I go through the menus and launch the game, this is when the problem starts.  Once I start moving the cursor in the game, trying to control my demigod... the cursor dissapears and my mouse movements control the camera.  If I open up the menu, the mouse works fine and I can see the cursor but as soon as I go back into the live game, the cursor dissapears again.  If I alt+tab out of the game, the mouse cursor is stuck in the middle of a screen and I can move it around but as soon as I start moving it it jumps back to the middle of the screen.

The other thing I should mention is that this happens very randomly.  One day I can play and the next I cannot.

If anyone has had the same problem please let me know how I can fix this.  Its pissing me off cause I cannot play the game and I have to launch to actually find out if it works or or not.  THank you!
