Overview

When PivotalClient is kept idle for an hour or more, upon clicking of a subject or a topic,  nothing happens and the application stops responding. Relaunching the Pivotal Client resolves this issue. One or more exceptions and errors occurred while the application stopped responding:

Environment

Pivotal Client 6.5.2.1
 

Root Cause

As per the Research & Development analysis, there is a null check missing while getting the controls from 'Find Searches' tab (introduced in 6.5.2 release), which causes the issue. 
 

Resolution

Attached to this article, find the Pivotal.Engine.UI.ActionObjectsModule.dll file for version 6.5.3.7. For Packaged Client, replace the file in the paths: 
C:\Program Files (x86)\CDC Software\PivotalClient\PivotalClient.PerMachine\exe\bin\StandardForclickOnce
C:\Users\\AppData\Local\CDC Software\Smart Client\PivotalClient.\exe\bin\Standard
