I'm having some very frustrating problems with my Logitech g600 and I've looked at all the threads on this site about the glitches having to do with this mouse and none of them have been helpful. My problem seemed to be, at first, that my left click was stuck but I've come to find that this is most likely not a hardware issue. If I plug in the g600, my pc just starts to act strange, i can left click certain things like the task bar items or the windows logo at the bottom left but not windows open on the desktop. If i unplug the mouse and plug in another mouse, sometimes it works and sometimes I have to restart my whole computer to regain my left click which is horrible to have happen while gaming. I've tried using the mouse on a separate computer and it did the same thing which is worrying to me. Please, if anyone has any advice I would appreciate it.
