We recently made a change to Version 15.3 that improves the performance of Secure Clients in Tabs3 and PracticeMaster. Previously, non-managers may have noticed reduced performance the longer they had the program open, depending on the number of Secure Clients in the database. With the recent change, performance will be more consistent in all areas throughout the day.
If you know of a firm that utilizes the Secure Client feature, encourage them to download the latest update. You might become their hero. Version 16 also has the same Secure Client performance improvement.
