You're definitely not using Entourage 12.1.8, since we're only at 12.1.5 right now.
The
Entourage MVPs have a bunch of guidance for Entourage issues. You should probably start with their
troubleshooting basics information. Then you can check out their
main database page for a pretty good list of database-specific troubleshooting information.
To stop My Day from opening on launch, go into My Day. Go to the My Day menu, then select Preferences. On the General tab, remove the check in the box for "Open after computer logon".
Also, remember that if you've purchased Office 2008, you get two or three free calls to tech support. (Sorry, I can't remember the exact number!) We've got Entourage experts on our tech support, so if you're stuck, they'll be able to help you out. Alternately, you can try to post your questions to the
Entourage public forums -- lots of Entourage experts hang out there, and there's more of them so they're quicker on responses than I am.

Nadyne.
