The trackpad on my 2013 11" MBA seems to be having more problems as time goes by. It often thinks I'm right-clicking (two fingers) when I'm really only using one finger. And using the two-finger right-click gesture seems to be very unreliable now, have gotten into the habit of control-clicking instead. It sometimes mistakes rapid movements as other multi-touch "swipes" too. None of this is enough of a problem to warrant repair or replacement, but it can be rather annoying. I never liked trackpads to begin with. Anyway, is this a common thing as these models age? Have read about swelling batteries causing problems, but I don't see any evidence of that and still get good battery life. I have always used a mouse when possible, so this is something that I can live with. Just curious if others have noticed something similar on 3 or 4 year old MBA's?
