[Visualpython-users] active stereo

[Bruce S. <Bru...@nc...>]

The latest VPython on Windows has an intermittent problem with 'active' 
stereo (shutter glasses). Sometimes you get a black window, then 
rerunning the program often makes the display work properly. The only 
workaround at the moment is to revert to an earlier version.
