[Ardour-Users] Waveforms change places but will not move freely

[ANDERSON GREGORY]

I believe I hit a setting by accident but am unsure what 
it was.  Now whenever I try to move a waveform it will 
trade places with the waveform next to it.  However, it 
will not move freely or where I want it to go.  It would 
be great if someone could tell me what I hit so I could 
fix it.  It made doing anything productive well out of 
reach.
