Mic,

I've checked this through, and you're right - if you run through the sequence once, and go back to the beginning, then the first sequence gets stuck.
May I suggest a workaround?
Put in a setup cue that sends the library or file parameters to look in to space for a fraction of a second and then go back to the cue 1.
So you could have:
Cue 1 - Setup cue - file/ or library look into space
Very short wait time to:
Cue 2 - The first sequence
Cue 3 - Second sequence
So Cue 2 has a v. short wait time.

See if that helps.

Best wishes,

Hugh
