Below is an example of the output when Command Window. This is really odd, as I left Octave GUI in its frozen state and looking at it an hour or two later, the text had all shown up and the terminal no longer frozen:

Tagging the version where command line freezes (but I didn't bisect, so it is this version or sooner): 24019 (fc4ba8b1ff87)

When I edit a variable in the Variable Editor, the Command Window interpreter no longer accepts any keystrokes. Other windows function, e.g., Editor.

I think once I typed in "tv" to the variable editor table for x, where

and saw a strange printout like "cannot edit that type of variable", but I can't reproduce it to know exactly what the message was so that I may grep for the code where it occurs.

When the Command Window freezes, there is no way to exit the GUI, except resort to the system process termination. In this bug report:

https://savannah.gnu.org/bugs/?44485

I added a timer which would allow escaping from this frozen scenario. Of course, that has nothing to do with the bug at hand.
