you mean it is not there? um i thought it would be there i guess i just took it for granted that it was.

but your right there should be a message telling everyone on the data burning cd's that the session is being closed.

When burning a cd/dvd, you eventually get to the message: "Burning (100% done writing)", yet the process is still proceeding.
I think that the data trailer is still being written. This can take quite a while, and the user may think that something is wrong.

I believe that an additional "progress thermometer" message is required during this time.
