I have 2 Habu mouses and after time, they will start double clicking on a single click, not a problem in game but incredibly annoying when trying to select a single item, such as a shortcut, and having it open instead of selecting it. I believe my brother has had the same problem. I still love the mouse and would actually spend $30 on one if I needed to.
Edit:
Side note, typical Friday maintenance, site is down...
My post says 11:02am, yet it isn't even 11am yet. I posted this more than a half hour before 11am EST. Someone who responded to me has their post show up before mine, that is some serious bugging by the site...
