I've been using my trackpad on my unibody MBP for about a year now. I use the 'tap to click' setting, as I don't see a need to 'click' the pad when I can just tap it. However, today something very strange started happening - when I tap with one finger to do a single left click, it reacts as if I've done a middle click, activating the 'expose' function. Two finger tap still does right click, and my multi-finger swipes still activate their preset 'expose' functions, but single click has somehow broken....

Furthermore, adding to the 'weirdness', if I 'tap to click' on the left side of my trackpad, it works as it should, but anywhere towards the middle/right malfunctions as described above - I've looked to see if I've inadvertently ticked a function that causes it to work in this way, where a tap on the left, middle or right of the trackpad causes it to react as if it's doing a left, middle or right mouse click, but can't see anything....


Any ideas???!
 
Sorry no ideas to help, but this is does happen in both tap and click mode- the trackpad sometimes confuses one and two fingers, don't know why (or how; don't have sausage fingers or anything).

Yeah, not great but at a guess I get it every 20-40 clicks or so, how often is this happening?
 
The same thing happened to me 5 mins ago. Resetting PRAM helped.

Turn off your macbook. Turn it on again while simultanously pressing and holding the four keys Option, Command, P, and R until you hear the startup gong.

Good idea - will try that! :)
 
Does regular clicking work okay? If you have a removable battery on your Macbook, try taking it out and see if the problems persist.

I had a similar problem that grew worse over time. It turns out the battery was swelling and putting pressure on the trackpad. Apple replaced it, no questions asked.

Just a thought.
