I'm not sure what is happening to my mouse, the mouse of the MX Duo (says Mx700 on the mouse itself). Gradually over the last month maybe, my left button would sometimes get stuck but it was not really noticable. This morning when I started to use it, my left mouse button would get stuck and would continue to click like when playing a game it just keeps firing the damn weapon. Anyone had problems like this before and know of a way to fix it such as cleaning or something? I really would not like to buy another mouse.
