Trackpad suddenly over is sensitive

Trackpad suddenly over is sensitive

Tried all the settings in System Preferences and combinations of them to no avail. Single clicks are interpreted as double clicks. Sometimes just touching it causes an action that should require a click. Positioning the cursor almost always selects an entire word (sometimes an entire line) requiring a forward or back arrow to get to where I want to go. Zapped PRAM. Can't find anything obvious in Library. I'd like to think it's the trackpad, itself, but it could be whatever processes the signals to/from the trackpad. Everything else works perfectly (or at least the same as it always has). I added no software immediately before problem started and don't even remember upgrading anything. Still running 10.4.11 as I have one program that will not run on 10.5+.

"OVERSENSITIVTY :

Just uncheck the ""press to click option"" in the ""One finger"" section of the trackpad's system preferences. The oversensitivity is killed definitively (but you will have to click instead of just touching the trackpad)

HEAVY PRESSURE REQUIRED to produce active clicks

It does not come from the battery. It is caused by a failure in Mac OS X 10.6.8 update ( 10.6.7 is much more finder friendly than 10.6.8).

To solve this bug, just trash the trackpad's preference file (.plist) which is located in the Preferences folder of your user's Library and restart the Mac. The problem may come back one day, then, it will just suffice deleting this file again.

As evidenced by the profuse internet calls for help, thousands of people have been seriously bothered by these two problems (especially the second) for many months. Why does'nt Apple address the matter and provide an answer ?"

I don't know how I found out but I discovered that early MacBooks such as this one (which was the second edition) suffered from a "bulging battery problem" that Apple considers a safety issue. From a practical standpoint, when the battery bulges, it presses against the bottom of the trackpad and causes problems that can be a button that is difficult to press, an unresponsive trackpad, or as was my case, an over-sensitive trackpad. All you have to do is sight across the bottom of the laptop. If the battery is protruding, Apple may replace it for free (or, at least its worth asking them before trying something more expensive). Anyway, they replaced mine for free. Hope this helps should anyone have a similar problem in the future.
