[Ti] Trackpad freezing

[Lorne Chapman]

I had similar symptoms on a 1.5 Mh  PB purchased in Dec. 2005.  I use  
a Wacom tablet when it's on the desk so had been putting up with the  
problem - but it was a pain whenever the computer was used elsewhere.  
I'm running 10.4.6.

Believing this to be a hardware problem I called AppleCare - assuming  
the 1 yr warranty would apply. Instead of it being an admitted  
hardware problem I got taken through a reboot from the original  
install CDs to run Disk Utility - repair. This seems to have improved  
operation quite a bit - it is now acceptable although nowhere near  
the trackpad response on my old 667 TI. For this Apple charged me for  
a one incident call. To me this is a rip off - the trackpad is  
hardware - it should run and Apple should ensure the hardware runs  
through progressive software updates without charging  customers if  
they blunder with an update.

Anyway, that aside, people with the problem might try the above  
procedure before getting Apple's help.
