Cognos 11.0.11 'Recent' list unstable.

[DavidHull]

Hi all.
We're running CA11.0.11 on Windows Server 2012 R2.

We have been getting issues with the 'Recent' list on the main page of the Portal.
Most of these are due to the 'admin' in a group moving the base reports around within their folder structure. That groups users suddenly find that their 'Recent' report link no longer works.
Its easy enough to ask the users to simply go and find the base report and run it from there, thereby refreshing the link to the "Recent" report and things are good again.

However, recently, some of our users have had their "Recent" links go awry on them, and the base reports have not been moved.
As before, it's easy enough to ask those users to run the base report from it's folder, but I have no explanation as to why the link would fizzle in the first place.

Any thoughts /  suggestions?
-D.
