Hi André,
Good to hear things are moving along on the Win32 implementation.
W.r.t releasing the graphics context, I have added the releaseContext
method to GraphicContext, this was essentially for getting the
stopping and starting of threading working under X11, and no doubt
important on other platfoms to. I didn't put a releaseContext in the
thread exit code though, I'll add this to the end of the
GraphicsThread::run method. Try adding this to you local version to
see if it helps.
Cheers,
Robert.

Hi Robert,
Things are progressing well for the Win32 implementation of the
GraphicsWindow class. It's likely that it will be submitted sometime next
week (I still have a number of things to implement/complete and a bunch of
cows to render before getting there though :-) ).
FYI:
During a multi-thread setup test, I noticed when closing a window that the
current OpenGL rendering context does not seem to be released by the
cancelled graphics thread that owns it. This causes the thread that close
the window to fail grabbing a rendering context for it. Specifically, this
happens here:
void GraphicsContext::close(bool callCloseImplementation)
{ <-- called by the "main" thread
...
setGraphicsThread(0);
...
if (callCloseImplementation &&...)
{
makeCurrent(); <- this will fail because the rendering context
associated is still owned by the graphics thread that just went away
...
}
...
}
I'm still at the beginning of the investigation for this issue, so I could
be wrong, but it does look to be the case for the moment.
André
