Express Messages on BBP Web GUI

[Dave Aitken]

Hello everyone,
 
I am currently working on a BBP 2.0b system, where the user will log onto
the system via a web front-end. They will not have access to the SAP GUI.
If I send an express message to the user, it does not provide a pop-up box
to indicate that such a message has arrived. Yet if you are logged on using
the SAP GUI the pop-up box does appear.
 
Has anyone come across this before?
 
Thanks for any response,
 
regards
 
Dave Aitken
