In the event of a multiple warning situation, the message center will

seconds.
The message center will display the last selected feature if there are no
more warning messages. This allows you to use the full functionality of
the message center after you acknowledge the warning by pressing the
RESET control and clearing the warning message.
Warning messages that have been reset are divided into two categories:
