Details:

Any type of plotting freezes the command line output in the GUI, even though
keystrokes are accepted and processed after the window freezes:


graphics_toolkit ('fltk')
plot(20*rand(4))


Now type


exit


Relaunch GUI (I'm using "run-octave" after a build):


graphics_toolkit ('fltk')
plot(20*rand(4))


Same thing.  Originally I thought this was a color map issue, but I no longer
think that:
