Details:

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


>> x = 500*eye(4)
x =

Diagonal Matrix

   500     0     0     0
     0   500     0     0
     0     0   500     0
     0     0     0   500


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:

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