A client asked: Prior to our upgrade, some F2 lists showed over 25 entries. After the upgrade, they only show 10. What could be causing this?
This could have been caused by a change to the Display Limit of maximum records. See below:
* Go to Tools > Configure > System settings > Display tab
* Change the value of 'Maximum number of records shown in Contact Search Center,
Activity List, Contact list, and Contact records tabs'
* Increase the limit from '10' to '2000' or more
* Click 'OK'
This will now display up to 2000 records in any of the lists, including the F2 lookups.
