I have a new HP box with vista x64, it came with a trial office 2007. I installed office 2003 with out any errors noted. Outlook and Excel seem to work ok however Word will hangup after two letters are typed, and then gives a NOT RESPONDING message. I uninstalled the office 2007, and using office 2003 uninstalled and reinstalled word 2003. The problem remains ,two letters and it quits. What do you think?
