<sigh> I apologize for the lameness of the SourceForge bug tracker. "Close comment posting" is unchecked, so I'm not sure why it isn't letting you comment.

The first call to glXMakeCurrent() with a window ID should cause VGL to pick a default image transport. The default image transport is set in the constructor of pbwin, based on the Display * passed to glXMake[Context]Current(). pbwin is instantiated within the body of glXMake[Context]Current() if a window is passed to that function and the window does not already have a pbwin instance attached to it (which is the case if that window has not been made current before.) However, if you're calling glXMakeCurrent() on non-visible windows (why?), then that would explain the behavior you're seeing. ------------------------------------------------------------------------------ Write once.
