[QLab] Relative fade strangeness

Hi Chris/Kevin

I think Kevin is right here - somethings odd happens when re-running 
relative fade cues.  I was curious so tested in the following way.
Cue List:

1)10 min wav file of 250Hz sine wave. (at 0)
2) Rel.Fad Up +15
3) Rel.Fad Dn -15

run the first time at the end of the sequence you end up back where you 
started level wise.
re-run Q2 and the level jumps to -15 and fades up to 0dB (original level).
re-run Q3 and the level jumps to +15 and fades down to 0dB.

So repeated re-runs of Q2 will continually jump to -15 and fade back to 0, 
instead of adding +15 and then adding another +15.  Same behaviour for Q3 
(+15 and back down to 0 over and over).

Creating a Cue list
1)10 min wav file of 250Hz sine wave. (at 0)
2) Rel.Fad Up +15
3) Rel.Fad Dn -15
4) Rel.Fad Up +15
5) Rel.Fad Dn -15

Everything works as expected (no level jumps) until re-running any of the 
relative fade cues.
----------
On another note, re. levels being copied between cues when setting targets 
for fade cues.
1) Create Sound Cue A
2) Create Fade Cue G (absolute or relative)
3) Drag sound cue A to fade cue G to set target.  Fade Cue levels are set to 
sound cue values.
4) Change fade cue G to -8 (for example)
5) Create 2nd Fade Cue H.  Drag Fade Cue G onto H.  Levels of H set from 
Sound Cue A and NOT the Fade Cue A - as I imagine would be the logical 
behaviour.

...and as an extension to this (yes, there's more!) when copying fade cues 
identical copies are not created because the fader levels within the copied 
cues set back to the Target Sound cue levels.
------------
Cheers,
Mike
