Dealing with Large Databases
The objective of the Contact Selection Viewing is to provide users with a list of the contacts that will be converted for a particular user. If you have Convert All enabled, all the contacts will be listed on the database. However, if you have over 20000 contacts in the database, the listing will take awhile. You can press on the Stop button to stop the listing and still see the front end of the contact list.

In many Act! databases, there are a lot of empty records and these records will display at the beginning of the list. Scroll down the list and you'll see the real contact records.
