I've never used sync points in soundbites before.
I've read the manual and looked through the archives here.
I'll save you most of the details -
I have about 20 cues (mono soundbites) where I have inserted sync points.
When I select them, right click and "export selected soundbites" as WAV de-interleaved
(as there's no mono option I can see) the soundbites are exported
but the sync points are lost.
Alternately, when I try to select the soundbites and drag to a finder folder DP crashes every time.
DP also consistently crashes when I select the soundbites and drag them to a Clipping folder.
I'm screwed whatever way I go.

Any help appreciated.
