I have a 3" happs trackball and a hagstrom ke-72T encoder.
I took the mouse apart to give it a cleaning, put it back, all is hooked the way it started, and now the x-axis is backwards, ie: roll left mouse pointer moves right, roll right mouse pointer moves left.
I swapped the opti boards, didnt expect that to be the problem. Problems stays with x axis.
What am I forgettnig?
