SUMMARY
If a DOS Enhanced user has the Network Information (NIF) Screen up and receives domain-wide broadcast messages (for example, NET SEND /DOMAIN:MYDOMAIN &quot;TEXT&quot;), the user does not get a popup until he or she quits the NIF screen. Once the user exits the NIF screen, a popup that lists all broadcast messages that were received while they had the NIF screen up will be displayed.



MORE INFORMATION
This is not the case when a directed message is sent to the user (for example, NET SEND USER &quot;TEXT&quot;). The user will get a popup while the NIF screen is being displayed.

This is considered to be correct behavior. Domain-wide messaging is implemented via the mailslot API calls. The messenger checks its mailslot to see if there is any data in the mailslot on Int 28s, and because the NIF doesn't generate Int 28s in its idle loop, the messenger never gets a chance to run; thus, it doesn't pop up until the NIF exits. At that time, the messenger will run, see the message in the mailslot, and pop it up.
