Thank you so much. You provided all the help I needed. I’ll follow all your suggestions, and have already opened a DTS with Apple’s own sample code as a demo of the problem. In past experience with them, If the issue is an Apple bug - they usually “refund” you a DTS incident.
One curious thing though — weren’t apple coming off openGL and didn’t they claim Mac OS El-Capitan is all “Metal” now?
B.T.W - for some strange reason my e-mails to the list appear twice — I don’t know who is duplicating them…
