Summary
If you are using Laserfiche Client 6 to view a Laserfiche 7 repository, opening a document and clicking on a thumbnail may display the previous image.
Cause
This issue may occur in documents that contain both black/white and color pages. Due to the way the Laserfiche Server reports the next page number, Laserfiche Client 6 may incorrectly read the thumbnail page number.
Resolution
There is a hotfix available for Laserfiche Server 7.2.1. The fix is an updated version of LFEng.dll (version 7.2.1.415).
Important: A previous LFEng.dll hotfix (version 7.2.1.410) contained a fix that required changes to the SQL database table structure. Subsequent versions of LFEng.dll expect the updated table structure. If you are applying a subsequent LFEng.dll hotfix directly on the release version of LFEng.dll (version 7.2.1.407), you must first update the table structure using the SQL scripts provided in Knowledge Base article 1011713.
To update Laserfiche Server 7.2.1
