problem with hold in gnuplot

[Mario Storti]

Hi all!

When I issue  'hold on',  subsequent  'replot' commands give plots  or
blank screens  in a rather random sequence.  Here is a transcript of a
typical  session.  (I inserted  lines  containing '(plot)'  or '(blank
screen)' depending on the result of the given command. )

================================================================

Octave: version 2.0.11 (i586-pc-linux-gnulibc1).
Gnuplot: 3.5 (RedHat package 3.5-5)
Linux: RedHat 4.0 (Kernel 2.0.18)

Any hints?

(BTW, I visited the Octave Web page recently. Very cool indeed that
rotating thing.)

Cheers,

Mario
