Description

Replace this section with a description of the problem, including:

• What you did: launch Octave-6.2.0.app in Finder with Editor window undocked in previous session.
• What you expected to happen: to be able to copy/paste in command window
• What actually happened: cannot cmd-copy in command window, until I toggle to the editor window first, and then back to the command window
