Okay here's the problem. I have a system running Windows XP Professional. Right now, everytime I right click on anything it freezes and I have to end task. This problem occurred a couple of hours after I put a new Logitech MX 700 mouse on my computer (hooked up through USB). Here's the thing I was replacing another MX 700 mouse. So, I didn't install any new software or anything. Since, I was replacing one mouse with the same kind I didn't expect any problems. Can anyone figure out what's going on? P.S. The mouse works fine for everything else but the right-clicking.
