Issues with Logitech K400 keyboard/touch pad

[Sonikku]

The touch pad seems very fickle sometimes. I want to use it to move the pointer when I'm on the couch, but sometimes it gets locked into scrolling up/down a page instead and I can't get the pointer to move. What could be causing this?

How far are you from the computer where the receiver is plugged in? I know that I've had connection issues with Unifying devices in the past. I have that keyboard and haven't had any issues, but I only ever use it about 3-6 ft from the computer.

About 8 feet. But the thing is all the other keys always work even when the touch pad is deciding to scroll instead of move the pointer.

What OS, and do you have SetPoint installed?

did you get water/sweat/etc on it?
my k400 touchpad seems to not respond when my fingers get slightly sweaty.
