Details:

Octave GUI waits until 'Command window' finishes before performing some
actions indicated by the user meanwhile. In particular, "saving a file in
'Editor'" or "exiting the Octave GUI".

How to reproduce it:

1.Type


>> pause


or something computationally expensive which will not finish before you ask
the action to the GUI.


>> for i = 1:1e8; a=i; endfor


2. Ask the GUI to exit or save a file.

When the command finishes (for example by pressing Ctrl+C), all previously
indicated actions are then correctly performed.

I think it is an undesired behavior. First times I faced it I didn't
understand why the GUI was not responding. If it is intended, I think it would
be helpful a dialog informing about why Octave GUI isn't doing what I intend.
Then I could act consequently.

I describe an use case to show why it was confusing to me:

I have an Cctave program with some "pause" commands to check some intermediate
results. I notice that results are wrong so I modify the file and try to save
it without caring about finishing execution of paused octave program, Saving
is not responding and I cannot realize why. I think Octave has some problems
so I try to exit and launch Octave GUI again, but exiting does not work. I
don't know how to proceed then.
