MacBook Pro Trackpad Clicks Not Responding

Clicks on the trackpad of my MacBook Pro were becoming less and less reliable. That is, about 1 out of 3 clicks would not register, unless I held the button down for more than a fraction of a second.

Apple Support Discussions provided a solution that works for me. See topic Official *Trackpad Click Not Always Registered* Thread for details.

Basically, you need to set the Double-Click speed lower. I set mine to the 5th tick mark, and it works fine now.

Update: Bad news is that this only helped for awhile. After a few reboots, the problem has returned, even though the Trackpad settings are at their new, lower position. I will have to continue the search for a solution.

Update 2: Good news is that there is a bizarre workaround. If you have one of your hot-corners set to start the screen saver, drag your mouse to that corner. Just as the screen-saver starts, pull the mouse away, so that you don't have to enter your password. You clicking behavior will be restored to normal. Yay.
