Can't drag a MIDI track from one project to another

I’m trying to drag a MIDI track from one project to another. This pile of junk won’t allow me to do it. Both are saved in the current version of Cubase. Does anyone actually test this product before it’s released?

Use Files/Import/Tracks from Project

Or Ctrl C, Ctrl V the part:

select the part, copy, go to other project, place cursor on the track/place where you want the part, paste, done!
