I cannot remove messages from the agent "Word searching" list this morning. Steps to reproduce:
1) log into UT
2) enter message area
3) click on agent button on UT toolbar to view list of agent messages
4) click on "Check" button to mark them all
5) click "Remove" button to remove them all
6) click OK on "Please, confirm deletion of marked items?" dialog
7) instead of messages being removed, now get a dialog box that says "You have to login in order to proceed with this option." Messages are not removed from the list.
