My optical mouse which has behaved itself since I installed it, about 4 months ago, has now decided to move the pointer all over the screen at random and sometimes lock up, I have to wait a few seconds or move the mouse about to get it to respond.
Any help bringing this rodent to heel will be appreciated.
No batteries, corded mouse, I have cleaned the sensor window, I have used a sheet of plain paper to use it on since I installed it, no broken tail either, I don't mistreat my animals :-) BUT, I think the USB cable into the keyboard could have been a bit loose, I have a sliding shelf for the keyboard and this could possibly have loosened the cable.
I will use it for a while and see if that was the problem.
I think optical mice work by recognising differences in the surface they rest, plain paper wouldn't offer the differences they expect. Try using it on a bit of newspaper or something nice and colourful.
