System Maintenance

PRPS users who have a session that is idle for 25 minutes will receive a pop up warning message requesting the user to continue their session by actively clicking on the Ok button. The pop up warning message will display a 5 minute countdown informing the user to actively click on the Ok button before the countdown ends. If there is no action by the user, then their session will end and if they want to continue the session, they will need to close their browser, reopen their browser to access the PRPS site and log back in. If you had entered information on the PRPS page without saving, you will lose the information. If you have saved your information, then it will be available when you log back in. For additional information, see FAQs A15, A16, A17, A18 and A20.

If you have any questions, you can contact the PTAB assistance line at 571-272-7822.
