interaction with gnuplot

Hi All,

I'm on WinXP SP3 with emacs 23.1.1 and gnuplot 4.4.0 and gnuplot-mode 0.6.0.
I would like to use gnuplot from inside of emacs. To do that I'm trying to
use gnuplot-mode and have set (setq gnuplot-command "c:/Program
Files/gnuplot/binary/pgnuplot.exe") in my .emacs.

In a file in gnuplot-mode I press C-c C-l to send a line with "plot [0:3]
sin(x)" to gnuplot. Gnuplot starts and plots the function. However, emacs
remains blocked waiting for something. If I press C-g emacs returns alive
and I can continue. The same happens with every command I send to gnuplot.

To understand if the problem is with gnuplot-mode or with emacs itself, I
tried to run pgnuplot from inside an emacs shell (M-x shell RET). Inside the
shell I can execute (several) commands without having to press C-g after
every command, but I do not see the gnuplot prompt. Could this be the reason
for the abnormal behavior in gnuplot-mode? Any suggestion on how to fix
gnuplot-mode under WinXP?

Thanks,
Fede

P.S. I tried emacs 23.2 and gnuplot 4.2 as well with the same results.
