Hello John,
You can have a render context share lists with another context that has
existing display lists. You just need to pass in the context with
existing display lists as the first parameter to wglShareLists and the
new context as the second parameter. OSG should get the sharing right
automatically if you use OSG for the creation of your contexts. If you
create the contexts yourself, it becomes your responsibility to set them
up to share correctly.
Regards,
Mark

Guys,
wglShareLists requires that the context which IS GOING TO SHARE has no
display lists existing.
NOTE: See the italicized hglrc2 at this link:

This creates a massive problem if we start with one window and wish to
create more (sharing) later.
I don't think this is an issue on other platforms.
Does OSG watch for this, or do I have to code around the issue myself
in my application?
The examples which share contexts are great for learning, but they
also neatly avoid this real-world problem by creating their windows at
startup.
