I have a logitech cordless optical trackman.
(here) , and it has worked fine for years.
Well, starting yesterday, the left click button now also dose the foward comand at the same time. So everytime I try to click on a menu command (flie, edit, etc) it immediaty goes away. I have to click and hold to use the menu.
The real pain-in-the-ass is when I hit back, then try to click a hyperlink, it wont work, it goes foward instead.
I "updated" the drivers (they were the same), and battery level is good, and no other problems.
The only weird thing I noted, is my system is showing 2 mice in device manager, but if I disable either, the mouse stops working......
