Hi Christian,

--refid should be the correct flag, but as it's not used very often
there is perhaps a bug. Can you send us a pair of AIDA files and the set
of commands that you are using, so that we can try to reproduce/bugfix
it?  Hopefully if there is a bug we can fix it in time for the next
release (not too far away).

Cheers,
Andy
