Jesus I was getting frustrated for a couple of days as to why my mouse was not working quite right.
I thought it was the surface for the mouse but even a flatter surface did nothing. Looking at the mouse trying to figure out what was wrong I tried replacing the battery, that didn't work either.
So now finally I noticed that the laser tracker was partially obscured by a feather that managed to get caught in there. It's out now and my mouse works like a charm! but yeah, fookin feathers mang.
