Popup Message Queue Can Only Receive 6 Messages

SYMPTOMS

The messenger service accepts and displays at the most six messages. If it receives more than six messages, and if the previous messages are not acknowledged (by choosing the OK button in the popup window), all messages sent after the sixth message are ignored and not displayed.

This can also show up with other combinations of messages and confirmations, such as in the following transaction example:

   Sent                  Acknowledged  Displayed
