Depending on your configuration, you may be prompted with the following message after a period of inactivity:
Your session appears to be inactive. You will be logged out in 30 seconds.
In order to stay logged on, you must either click Stay Logged In or press the Enter key. If the Stay Logged In button is not activated within the allotted time, you are logged off of the Web Client.
CAUTION:
In Firefox, the message may not be displayed if the Web Client is minimized behind another application that is maximized. In this case, you may be silently logged off when the timeout threshold is reached. Ensure that there are no maximized applications in front of the Web Client.
