gnuplot reload

[Martin Weiser]

Hello,
sorry to bother you, I am a Octave newbie and I have not found this in the 
manual.
How can I reload gnuplot after its crash down without having to restart Octave?
I am running Octave 3.0.0, on Win 2000, installed as bin (no compilation on my 
side).
After gnuplot crashes or just prints a warning, I am (Octave is) not able to 
run it anymore, until Octave is not restarted (Octave is running  and
working, but gnuplot does not produce anything apparent)
(command to octave to plot something->crash of gnuplot->command to octave to 
plot something->no response of gnuplot)
Thank you for your patience.
Martin Weiser
