Thanks very much Grazie,
Actually I just found out a workaround. Here's the deal: I edit a local weekly TV magazine...one for a CBS affiliate and one for PBS; CBS wants 02:03 between the 3 segments for ads, so I usually (with no problem) PTP the PBS copy first and then split and insert the 02:03 of black between. This time however it made me pull apart all tracks a little (after splitting) to get the volume envelopes to follow the audio. Not a big deal, I just need to remember this.
Thanks again Grazie,
Randy
