I know this might be the wrong place to ask but I recently modified
the ogl example from wxpython and it works fine in spe but when I call
it from other programs it wierds out because of the run.py thing they
have set it up with doesn't work when I call it from an external
program (including .bat files). when I call it outside of spe I
manage to just get a box without the tracker part. It is so close to
out right theft I was hopeing I could just tweek something to make it
work for me. Any help would be apreciated (I am trying to call it with
tracker.py bay-at-night.csd )

<h2>Object Graphics Library</h2>
The Object Graphics Library is a library supporting the creation and
manipulation of simple and complex graphic images on a canvas.
<p>The OGL library was originally written in C++ and provided to
wxPython via an extension module wrapper as is most of the rest of
wxPython. The code has now been ported to Python (with many thanks to
Pierre Hjälm!) in order to make it be more easily maintainable and
less likely to get rusty because nobody cares about the C++ lib any
more.
<p>The Python version should be mostly drop-in compatible with the
wrapped C++ version, except for the location of the package
(wx.lib.ogl instead of wx.ogl) and that the base class methods are
called the normal Python way (superclass.Method(self, ...)) instead of
the
hacky way that had to be done to support overloaded methods with the
old SWIG (self.base_Method(...))
