When starting Safari it take 3-4 minutes to load Google - Then when I type in the search box, within the first letter or 2 it locks up again - sometimes says "Could not contact Spell Checker"

I updated from 10.3.9 to 10.4.11 3 months ago and all has been just fine but now I am getting these errors. Also when Safari is acting up, Mail won't operate properly.

If I set up a new user, everything works great. But I'd like to restore my Local Preferences if possible without losing anything.

Can it be done easily?
