Yes, the V1 and A1 are clicked, the blue button is clicked.
What's unique is that I can drag this one sequence of about 6 seconds with two clips, but I can't drag in another sequence that's 10 minutes with a lot of clips. When the blue button is unclicked I received this error: No Content in In/Out Range. When the blue button IS clicked I received no error but still cannot drag in. Using latest Premiere Pro.
