Thanks for the tip Dan. There was a problem with the file system. I 
booted from an install CD and ran Disk Utility -> Repair Disk. I had to 
run it twice. The first time it fixed some errors, but not all. I was a 
bit worried, but I ran it again and Disk Repair was successful in fixing 
all the errors.

thanks again,

Matthew
