I get the same utter slowness with the CPU pegged at 100%. It occurs on my file which is only 7.7MB. I saw it using 4.2.1 on a clean install of Leopard on a Powerbook G4 12" 867. As a result, I moved the file to a MacBook Pro 2.33 running 10.5 upgraded from 10.4.10. It did the same thing. I've just downloaded 4.2.2 beta 2 to see if the problem remains and it seems to.
