System Maintenance

PRPS users who have a session that is idle for 30 minutes or more–and want to continue the session need to close their browser, reopen their browser to access the PRPS site and log back in. You will not receive a reminder that your session has been idle for 30 minutes or more. 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 PRPS FAQs A15, A16, A17, and A18.

A future release will provide a warning message when the user is idle before the 30 minutes time out is reached.

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