Wow, 6 years ago Reo had this problem. I use my mouse more for graphic art than gaming, but the left mouse button still takes a beating. Two nights ago while painstakingly selecting pixels in an image the switch feels like it has sunken in the body. It is still functioning - ish, but it's more of a "short stroke" to engage the switch and very easy to double click unintentionally. It is definitely fubared. I've owned this mouse for approximately 2 to 3 years now and I love it. Anyone have a solution? Or, are there repair parts available with instructions? Can one still buy a Level 10M mouse? Thanks in advance for any help.
