OK, reading the release notes and such, and following the thread on upgrades, we are going to first move to 2.0 before we go any further with troubleshooting. We want the new features and I don't want to clutter the list with troubleshooting data twice. I will look at enabling debugging in the 2.0 install and try to get the upgrade done by Monday. We will move forward then. Thanks for the help. DAve -- Three years now I've asked Google why they don't have a logo change for Memorial Day. Why do they choose to do logos for other non-international holidays, but nothing for Veterans? Maybe they forgot who made that choice possible. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
