Just another observation.....on my Windows 2000 box, if I try to open
applications immediately after I've started the machine (eg. haven't
given the machine time to completely finish starting up), the
applications take a long time to start up (Outlook, Word, etc.). If I
allow the machine to completely come up, then start the applications,
they're up in a flash. (I'm a believer that if the message says "ready
to log in", the system should be completely ready - but I know it's not)
Maybe the scenario described here could be similar? Maybe give the
system a chance to finish coming up and then start the application.

It won't know until it checks.

Remind us: what version of Windows do you use and what is the name
of your database file?

Also: how do you know it is sluggish? I mean, tell us what is your
first encounter with the database after the machine has been
cold-started. What is it meant to do, and what does it do instead?
