Superb, thanks Peter. I've captured a session exhibiting the behaviour; for comparison a normal two-finger scroll is between: Event: time 1362909816.949923, type 1 (EV_KEY), code 333 (BTN_TOOL_DOUBLETAP), value 1 and: Event: time 1362909817.959870, type 1 (EV_KEY), code 333 (BTN_TOOL_DOUBLETAP), value 0 Around here, I see a false click: Event: time 1362909818.577892, type 1 (EV_KEY), code 333 (BTN_TOOL_DOUBLETAP), value 1 and scrolling here jumps forward ~5 lines every 5 lines (this is surely not a feature?) Event: time 1362909820.148825, type 1 (EV_KEY), code 333 (BTN_TOOL_DOUBLETAP), value 0 I've uploaded the log to http://quora.org/evtest-bcm5974.log if you're able to find anything interesting. Let me know if I can get any other/better debug. Many thanks!
