Had exactly the same issue here (optical sensor stopped working out of nowhere). It turned out that the "thumb button" was screwed in a little to tight and started triggering the "gesture" command through the software the whole time, deactivating the optical sensor.  I disassembled the mouse and untightened a bit the "thumb button". Problem solved. :)
