it's a feature That's how it's expected to work.Any time I move my right nub to the right, it will act as if I have clicked it down (right mouse button)
This causes a menu to pop up that gets in the way. Is this a bug I can fix, or a hardware issue?
According to sebt3's link, the left nub is supposed to act as mouse movement, and the right nub acts as mouse buttons. Going left gives you a left click, going right gives you a right click, and going up or down acts as the scroll wheel.
This is actually probably a pretty convenient configuration once you get used to it.
I have spent most of my time in terminal using the right nub to scroll up and down, but would be interrupted by the right click menu popping upI'm surprised the OP didn't notice that moving the right nub left acted as a left click. Once you know that, surely it's fairly obvious what's going on. I do tend to think this ought to be documented in the wiki however.
