Is this the case?  Is there any way I can force the rgl window to have its messages received in the same thread?

Normally, all messages are on the main loop. Although apps can run separate threads, the OS loop is always on the main thread (that's why it's so delicate for us, because R also runs on the main thread so the two loops must be meshed together without blocking each other).

Can you send me a reference to the issue, please? I'll try to find some spare cycles to look into it later this week.

Thanks,
