[SEE]

there is a procedure, you may be aware of it but just in case....

first, Go to EDIT - Briefings - Add - (from the list pick e.g regular or Army Red)

it will appear on the right where you can re-name it, e.g Fighters.

create the briefing if you haven't already done so then press Save

Then, for the Group you want the briefing to appear in the Briefings screen -

select a way point and right click on the map - select properties,

this will open the 'View objects' for that group

scroll down and you will find a 'briefing' Tab and window showin None as the default

your briefing will be listed in that window using the name you selected, just dcroll down and select it.

Your briefing will be assigned to that group and should appear in the mission briefing screen.

I don't know of any problems with creating and displaying briefings.
