Can you please be more specific about what you're doing?
What are you dragging from what place to what place? Please be very specific, as I know of no area of the program called the Project Manager.
What model of camcorder is your video coming from and what format and resolution is it? How did you get the video from the camcorder to your computer?
Only program, that I know of from Adobe, that uses "Project Manager," is Premiere Pro. The Project Manager is very similar to the Archiver function in PrE.
