Title: Fix system text refresh when scrolling left and right on a touchpad

My touchpad is set up to scroll left and right when I drag my fingers around, which appears to register as extra buttons in mouse events. These cause the text pane in the system info screen to refresh as I was reading/scrolling.

This one-liner fixes that by ignoring buttons other than #1.
