Query: Just One Con

I love this mouse. The way it glides is perfect and I love the fact it comes with two battery packs and that there is no cover you need a screwdriver and jackhammer to remove. The one complaint I have though is the center(or scrollwheel). What is supposed to happen is when you press this button, it is supposed to activate some function, however it is nearly impossible to actually click. I am an avid fan of The Sims, and now The Sims 2. I like to rotate the camera, but you can hardly get the scrollwheel to click making the free rotate function nearly impossible to use. Other than that, I have no complaint and am a great fan of logitech. Their G15 is a great product to check out if you are an avid gamer.
