I just got the expansion pack (which is great

) but my mouse wheel does not work completely. I can zoom and scroll with it but when I am in the ship design area and you normaly can hold down the scroll wheel and move the mouse to rotate, but I can't. I was just wondering if anyone else had had this problem too.
I have installed the software that came with it and that fixed the other problems I had with it earlyer.
If any of you has had to rotate the ships using the arrows you know the frustration I am feeling.
