Geoff,
I am having EXACTLY this problem with one of my 4 1400's. I assumed it was
just a physical problem with the trackpad and had planned to replace it (a
ginormous PITA).
Can you send along more info? If you can cc: directly to [EMAIL PROTECTED],
I'd be most grateful. Thanks a heap!

Dear God!
Y'know, it occurs to me that "fixes" to many computer problems are not
going to be found in the wood shop. Strange as it may seem, notebooks are
pretty sensitive & complicated devices, and need to be treated with a
little care.
Sanding may fix it cosmetically, but I'd be very surprised if it fixed it
mechanically.
Trackpad areas discolored by friction or finger oil should be cleaned
carefully first. Occasionally, I have found this helps. A careful
application of Windex or similar cleaner on a lint-free soft cloth (NOT
paper towel;bits may come loose & get in the edges....not good.) often
helps. Be careful, as Fluxstringer pointed out, about getting liquid in the
edges of the trackpad. While probably not fatal, it just doesn't seem like
a good idea to introduce any type of moisture into a notebook of any kind.
If that doesn't help, and you're sure it's not a software bug (who knows?
stranger things have happened...see below...!) I'd look to have the
trackpad replaced. Hell, I've worn out mice in my time (and yes, I was
surprised!), so nothing lasts forever.
There are several places on the web that sell replacement trackpads for the
do-it-yourselfers, or it like me some days you just wake up with the
mechanical acumen of a turtle with a screwdriver, your local Mac shop would
probably install the new parts for a fee.
If it's a newer box, getting service can be a $$$ drag if not under
warranty.
But on the other hand, when a Ferrari blows a flat (and they do....!) you
don't fix it with chewing gum & duct tape.
*BTW, there is a software fix for some specific models with this kind of
problem...here's the first couple paras of the read-me. If this applies to
you, or you are interested (and running 9.2.2 & down....) drop a line. I
may know where the software is.
Important Information about Trackpad Climate Control
For Your Macintosh PowerBook Computer
What Is Trackpad Climate Control?
Trackpad Climate Control is a system extension that will reduce or
eliminate unexpected movements of the pointer caused by moisture on the
trackpad or humidity. The extension is designed for the Macintosh
PowerBook 190, Macintosh PowerBook 1400, and Macintosh PowerBook Duo 2300.
Who Should Use Trackpad Climate Control?
You should use Trackpad Climate Control if you notice the pointer moving
abruptly when you initially touch the trackpad or "jumping" to its previous
position when you lift your finger after moving the pointer or tapping the
trackpad.
Do not use Trackpad Climate Control if you have not had pointer-movement
problems on your computer. (The extension could make the pointer less
responsive when you use the trackpad.)
The extension works only with the PowerBook 190, PowerBook1400, and
PowerBook Duo 2300.
So there you go. Hope this helps.
