Resource Center will automatically log you out after a certain predetermined time. However if you have a "stale" window open (such as an active case). You are still able to "Add A Comment" and click "Post Comment" this will forward you to the login page but you will have lost the information you entered into to the form.

This dialog needs to be updated like many banking sites are that detect that the user timeout has expired behind the scenes and disable the "Post Comment" button or have a warning dialog to indicate that the user is about to lose content.
