Mouse Cursor stuck showing

[HavocBlast]

I have been having an issue with the mouse cursor showing all the time when I am in the view mode that mouse movements control the camera. I can see the cursor move across the screen and when it gets to the edge of the screen it slows the rotation of the camera. The cursor has been showing for me a long time but I have ignored it but now it is slowing my camera movements.

 

I did see someone posted a fix for 1.5.5 but I am sure that lua file won't work with the open beta version
