[visionegg] Dynamic function loading not implemented/supported on this platform

Hello,

I'd like to execute multiple scripts in succession. To do this, I'm using a .py file with multiple import statements, one for each script I want to run. For now, I'm just trying this with a moving target script (barscript.py) and a gratings script (gratingscript.py). If I import gratingscript.py first, followed by barscript.py, everything works fine. First the gratings run, and when they're finished, the moving target script runs. But when I try the reverse order (barscript.py, then gratingscript.py), barscript.py runs fine, but when gratinscript.py starts up, I get the following error:

File "C:\Python23\Lib\site-packages\VisionEgg\Textures.py", line 1194, in __init__
gl.glActiveTextureARB(gl.GL_TEXTURE1_ARB)
OpenGL.GL.GLerror: [Errno (1282,)] Dynamic function loading not implemented/supported on this platform

This error happens when creating an instance of the Mask2D class in the gratings script. When I comment out the mask instance, the error goes away and everything runs fine (but without a mask on the grating). It sounds like something's unhappy that stuff's been previously written to screen, but I don't know. I haven't tried this on another machine yet, I'll see if that changes anything.

I'm running the 1.0-cvs binary in Windows with Python 2.3.4 and all the recommended versions of the dependencies. Here's the full log of the error:

Any advice?
