Ok, so this is the first time I have an optical mouse. It is now about 4 months old and the scroll on it is kind of hard to use now, sometimes it middle clicks when I'm trying to scroll down (never up). I could take apart a ball mouse (or however you call it) with my eyes closed, but I don't want to take this one apart, it seems to complicated and don't want to mess it up. Does anyone know how I can ease the scrolling of it.

If it helps, this is my mouse: http://www.geniusnet.com.tw/product/...1.asp?pdtno=18
