Yeah, IIRC, most of the copy commands in CC only work within the current map. The Copy to Clipboard command lets you work between maps and between other programs. Let me know if you have any problems or questions and I'll see if I can help.

Edit: I just double checked - the default command when you left click the Copy button in CC3 is Copy in Drawing, which only allows you to copy and paste something within the current map. Right clicking on the Copy button brings up a list of all the Copy-related commands to select from.
