I'm staying the heck away from Vista until at least the first Service Pack gets released from MS - it's a MS product, they're always buggy initially.
Vista and Outlook 2002 don't mix, Todd - Vista only officially supports Outlook 2003 and 2007. There's a known issue with Outlook 2002 and Vista in terms of saving passwords - it won't so therefore you have difficulty downloading mail or have to keep entering your passwords. So other random quirks have been reported with Outlook 2002 and Vista. have you downloaded all the updates available for Outlook 2002 from MS's website? If that doesn't work, then you might be stuck upgrading your Outlook (or your MS Office installation).
Regarding your Lexmark printer - have you tried going to Lexmark's website and downloading the latest driver for your printer?
