I'm glad you posted this, because mine didn't notify me of an update... I went into the Preference itself and it still said there was no update... I went to the website and downloaded it...
I was going back/forth with Logitech over this mouse lagging and glitching... I sure hope this fixes it! Seems to be noticeably smoother after an install and restart... I'll report back if it starts lagging again.
