I've recently upgraded to Mac OS X Lion 10.7.2 and am now seeing the following mouse & trackpad "click" issue:


- My mouse click stops working (note: click function only) and this affects both my trackpad and wireless mouse click functions at the same time.


- This only happens periodically, in that if I restart my machine enough times (up to 5+) occasionally the mouse click function returns.


- The fact that this affects both my trackpad and mouse (always at the same time) makes me suspect this is 'software related' issue (as opposed to hardware problem).


- I have placed two calls to Apple now but the problem is still occurring, so far they have taken me through the following steps:

     - Call 1: (Note: I performed both these steps as directed by the Apple support team, which initally fixed my issue on start-up but an hour later the same problem started occurring again)


          - 1) Resetting System Management Controller (SMC) (see details below)

     - Call 2:

          - Apple support team suggest disabling 3rd party applications on start-up, which I have done but this has not fixed the problem.



I would love to know if other people have seen this issue OR even better can suggest a solution.  Alternatively if these is some way to monitor how 'mouse_clicks' are being processed at runtime that would be interesting also.

    You can ignore this question, I've think I've found the cause of my problem.


    (Embarrasing) - I had a second wireless mouse that I'd been using previously and I found that it was turned on in my computer bag.  I think this may have been the cause of the unusual mouse behaviour that I've been seeing.

    Hello. Thanks much for posting such a clear report.  I have a similar problem -- but for me it is more rare... like once in a 1-2 week period I have this problem, namely "mouse click stops working totally on both magic trackpad and built-in trackpad, and I have to reset."


    -- You post as a reply to your original post that you have solved it because you found that you had another wireless mouse on nearby.  You said it was embarrassing that that was the answer. But that doesn't really make sense. just because it is connecting to another wireless mouse doesn't mean that the other mice should stop functioning.  It's not really an answer...


    -- In any case, it doesn't answer my more intermittent problem. HOWEVER, I will admit that I had an additional bluetooth mouse set up under Bluetooth... but that additional mouse was turned OFF.  BUT, just in case it helped, I have now removed the configurations for two bluetooth devices I had under bluetooth (that extra mouse and my mobile phone, which I never connect to anyway.)   Perhaps that will decrease the computer getting into that frozen "can't click" state.  we will see...


    So -- thanks again, your post gave me an idea, namely to clean up my bluetooth configs so that I have only two items, the ones i really use:  apple bluetooth keyboard and apple bluetooth magic trackpad.   Fingers crossed.

    Thanks for your reply to your post! lol I had the exact same thing happening. I checked my computer bag. Sure enough, my Apple wireless mouse was turned on! Anyway, thanks again!
