Details:

I have loaded 3.6.4 - it works fine but old sripts that wored in 
3.2.4 fail to produce graphs.

In fact the problem seems very general.  I cannot get a plot first time I run
a script, I have to rerun the script to plot in the figure.  The problem also
works for command line plotting.

t=[0:.1:100]';
u=-1+0.02*t;
y=sin(0.2*t);
plot(t,y,t,u);
%y (y-axis) is plotted against t (x-axis)
%and u (y-axis) is plotted against t (x-axis).

I am running Vista, Octave 3.6.4 with gnuplot 4.6.

I still have 3.2.4 and the plots work fine.  Problem is I have a complex
script that I need 3.6.4 to run.

Any help with this bug appreciated.

Best regards


John
