It seems that for some reason, my duo always wants to scroll down. I've noticed this stops when I set the wheel on the left of the keyboard to scroll "None" lines in the configuration, but then, at the same time, this also disables my mousewheel which I depend on. This is making me nuts, when I browse the web, pages will automatically scroll to the bottom as if I've been using mousewheel down nonstop, if I play any first person shooters I'll cycle through all my weapons ... this is making me INSANE. I've tried pulling out the batteries, waiting a few minutes, and reconnecting. Is there anything else I can do? Could it have any relation to the large amount of wireless signals in my apartment? My roomie has an MX 700, we have a Wireless router, and I'd say I see anywhere from 7 to 11 OTHER Wireless routers broadcasting through my apartment.... any help would be appreciated.
