As title says, when I left click my mouse button the action is the same of a forward button click. It happens everywhere, in the browsers or in Explorer.
The configuration in the Logitech software seems fine, so it's probably a Windows problem, or driver problem. EDIT: I'm on Windows 10 Pro N 1607
I searched but found nothing similar and I really can't understand what is going on.
EDIT: I tried with another machine and the mouse have the same problem.
SOLVED: I uninstalled and reinstalled the Logitech Software
