Octave/Win32 new binary package (2.9.12)

[Arsenio Cesista]

Hi,
I downloaded the new binary and tried it on my laptop
(Windows XP SP2).  Here are some of the things I
observed.

1.  Installation

There is a prompt for choosing which linear algebra
libraries should be used but there are only two
choices - one for generic and the other for P4 - the
Octave 2.9.9+ installer included one for Pentium M.

2.  Plotting

I tried the sombrero function and got this message:

octave.exe:1>sombrero(41)
Could not enable OpenGL pipeline for default config on
screen 0
octave.exe:2>

I also tried running one of my old scripts for the
Lorenz equations and got the following messages below:

Could not enable OpenGL pipeline for default config on
screen 0
