File:  Excel
Severity:  Minor
Workaround: yes (reload the workspace)

Procedure to reproduce:
1) Hover mouse over file in workspace until menu appears...select "Rename File".
2) Type in new file name in space provided (once application goes into file screen).
3) Click "Edit" to open the file and do edits.

Error is obtained that the file with indicated name cannot be found.  I believe that the workspace is trying to open the old file name.  The file name that was updated was not populated to the edit function...hence Excel trys to open an old file name (link) that doesn't exist.
