Problem Description
As new data is added to a repository (both the collection and user repository in Analyst) the set of dynamic folders that reflect the products, applications, and versions in the repository don't update to reflect the new items. Likewise, if you delete all of the sessons for a particular item its dynamic folder isn't removed from the list.
Cause
Analyst determines the set of folders when the repository is initially displayed and doesn't re-evaluate it when sessions change.
Workaround
You can close and reopen the Analyst display without exiting Analyst by selecting Close from the File menu or clicking the close button in the upper right hand corner and it will redisplay the tree of dynamic folders, reflecting the latest data.
