As can be seen in the following clip: https://www.dropbox.com/s/72adss2uc1p22k5/test1.mp4?dl=0
The 1st time I Alt(to select video only)+drag to trim, it succeeds.
The 2nd time it causes the video and audio to get out of sync.
This is with Ppro CC 2014.1 and 2015.4.
I don't have yet 2017.01.
Can anyone confirm this behavior also occurs with 2017.01?
