I can’t figure out how to copy and paste line items from one GanttChart file to a different GanttChart file. I tried copying with the ctrl-c keyboard shortcut and pasting with the ctrl-v keyboard shortcut but nothing happened. I also tried using the Edit menu copy and paste in each file but that also didn’t work. I didn’t get an error message like others have commented on in the past. Nothing happens when I try to paste in the separate gantproject file.
