[Magic-dev] plow command not working as expected in MAGIC

[Gilbert Kowarzyk Moreno]

Dear all:

I've installed magic on a Linux machine and on a Mac machine. Here are
the versions:

magic-7.2.69 on OSX 10.3.4
magic-7.2.70 on Linux (Mandrake Linux 10.0, the kernel is 2.6)

The Linux version uses the tcl/tk interface (blue terminal), and I
believe during the GNU configure it found the OpenGL headers.

I installed tcl/tk on the Mac and after that the program ran, and it
seemed like it was working fine (though I am not sure it's using the
OpenGL libraries).

On both machines I've had the same problem: the plow command deletes a
chunk of my cell instead of plowing. The chunk is bigger than the box,
but located around the box. I tried on an older version (6.5) on an
older machine, and it works there fine. (I tried doing as per the
tutorials to test on both). 
I even installed version 7.1 on the Linux machine, and I had the same
problem...

Did I configure something wrong? I thought the plow module would load
automatically. Any help on why this is happening and what I could do
would be appreciated. 

Thank you.

Gilbert
