After you log in, QuickTrack will go through its database and make sure everything is up to date.  This is one of the reasons why QuickTrack is so beneficial; all these calculations that you would normally do by hand are done automatically.  There's no chance of human error and it's done in just seconds.

Normally this window would go away on its own once it's done calculating.  However, in this tour you have to click on it to continue.
