Gaming My mouse won't stop right clicking!!

A few days ago, i installed windows 7 ultimate 64 bit with no problems. However, today suddenly, my logitech v450 started acting up. it kept right clicking all over the screen, and then it stopped responding to clicking at all (but i could move the cursor around). when i unplugged the receiver, my touchpad would also act up for a bit, but then it would be fine. i checked if the mouse's buttons were stuck down, put in new batteries, reinstalled the device, drivers are up to date, tried a system restore, googled the problem and nothing! i also tried using another mouse, and that mouse works fine...
i'm pretty sure the v450 doesn't have any physical problems, so if it's a driver issue, why is it acting up now?
