Hi Sean,
that's what I am saying. It never really is 'under load'. It is just taking forever to select a clients data-page.
I would blame bad design and shrug it off, but this was way faster on the ancient w2k server, so I have no idea where it gets stuck.

You need to specific the full/local path to the database and as well as the database filename.
You really want to look at the fb_lock_print numbers when the database/server is under load.
