Hmmm, I use an external mouse as well as the touchpad, so it happens
quite often that I don't touch the touchpad for some time.
However, I never experienced (with current kernels; it did happen with
older appletouch versions) such behaviour.
Very rarely the appletouch driver stops working completly (sometimes
after a resume from suspend to ram, sometimes for other unknown reason)
and I have to reload the module in order to make it work again. But this
happens just once per week (and I use the laptop daily for 10+ hours),
so it never bothered me enough to look more closely.
I'm not sure if this changes something but do you have all the Apple
firmware updates installed ?
Sven: What Powerbook model do you have ? I know Johannes has the hi-res
Powerbook, and I have the slighly older lo-res Powerbook...
