Current session focus does not change on alternate session close

Hey guys,

Maybe I have some misconfiguration but since update to 13 I have noticed that when I logoff a session causing it to close, the tree and UI focus does not change to other open sessions.
The closing session does reveal the other open session in the workspace, but the tree focus remains on the old session
This means that the ACTION menu is one of the old closed session and not the session I am currently looking at
Even if i then click within a different open session's workspace, the focus doesn't change.
In order to change the tree/UI focus I am forced to click on the entry in the tree or click on the tab of the session.

Any ideas?
