Re: You know you're getting old...
Hi Wayne,
I use both a M510 and M705 Logitech at work. Just diff in size and weight, plus the 705 is a combo wireless keyboard AND mouse setup.
Btw, did U try checking the mouse settings (assuming Windows here) in Control Panel?
U can make changes there to your settings or customize it how U want. I'm sure U already know it, but sometimes we forget.
