Hi Seth,

I agree that it would be better to get to the bottom of this.  I just wasn’t having any luck.

The context locking issue has to do with trying to go to fallback canvas while in the middle of rendering.  But we do that (in both Tom’s and my case) as a result of catching an error from OpenGL.

So the locking issue isn't specific to Mac, just the error that leads to it (in my case; probably not in Tom’s case).

Cheers,
Jeff.
