I had the same sort of issue with a wireless mouse as well, but from logitech. The software that came with the wireless mouse and keyboard ran a little application in the background for controlling certain aspects of it. But, it could be used without installing that software at all. Furthermore, when I disabled that little program by preventing it from starting up (run the program "msconfig", or uninstalling it), I was able to rotate the screen once again. That little mouse control program was far more trouble than it was worth. Perhaps you have a similar issue, which could be solved the same way.

Most new mice come with special software, but 99% of the time windows can use the new mouse with zero problems without installing a thing, just plug in the new mouse.

I set my scroll button to 'Generic' in my Logitech software, and rotation works fine in the game.

Ok guys here's what has happened. I uninstalled all associated software, still no go. I tried many different button associations with no effect. Then i tried, just in windows associating the middle button with right click to ensure the mouse wasn't faulty. Nothing happened, so I'm thinking, faulty mouse. Back to shop get a replacement and get it all installed and the same thing happens.

Only thing i can think of is that for some reason Microsoft didn't think to make the scroll click compatible with all programs. Anyone know of any other way of rotating in the game, a keyboard shortcut perhaps?

Any help is appreciated as always, if i can't get this one to work, it's back to the shop and a different brand.....

Problem solved. Returned the Microsoft crap and bought a logitec set. Works a treat!!

I tried that and still wouldn't work right. Wasn't the 5 button one though.
