======================================================
My Octave installation information
======================================================
I downloaded then ran ...
... Octave-3.2.4_i686-pc-mingw32_gcc-4.4.0_setup.exe

I created the startup file ...
... .octaverc:
 cd 'E:\My Documents\Octave_3.2.4'

======================================================
My Octave "bug" report summary
======================================================

The screen output of my interactive Octave session is 
shown below.

After going to my desired working directory location,
I created a vector to plot ...

    x = linspace(-5,5,9)

My "bug" to report:

... my first plot(x) command produced ...
   (octave-3.2.4.exe:4 shown below)

    no plot output and "echoed" a warning

... my second plot(x) command produced ...
   (octave-3.2.4.exe:5 shown below)

    a gnuplot window is opened that appears "hung"
    with no plot shown in it

... any further attempt to invoke plot(x) yields no response

======================================================
My interactive screen output is below
