[visionegg] Re: error: OpenGL.ctypes

Hi Andrew,

If I double click I see the Python console to show up for a sec and then 
nothing. This is the reason to write the code in the console mode, so I can 
track the point at which I get an error. So far I`m stacked at the import _vegl

Hi Ilia,

I think there's something else going on. The VE (1.1.2) works with both
OpenGL 3 (except for one known small bug[1]) and OpenGL 2. So I don't
think that's the issue.

I think you're not running the demos properly. What you emailed looks
like a Python console session -- but to run a VE demo you would not be
in the Python console. I haven't used EPD before, but if it's like the
normal python.org Python distribution, you should either double-click on
the .py file or perhaps right-click it and select "Run as Python" or
something like that.

Are there any Windows users out there that have experience running the
VE demos with the EPD that can chime in?
