Followup question for playsound:
I believe I did what you suggested. In a saved project, I selected a part with yellow and then clicked on the Copy option. (To be sure I had copied the part, I immediately tested that by clicking on the Paste option, and the part was successfully pasted into the saved project.)
I then closed the saved project and opened a new project, hoping to save the selected part there. I was given no Paste,Save option, but in Edit menu is the Paste option -- but it remained grayed out and nonfunctional.
I tried this several times without luck. What am I doing wrong?
Thanks for your help and your patience.
