I seem to have found one of the causes of the 2d lock up:
When I join the race, on both accounts, I do so at the same time. I click to load 2d on one account, and live timing on the other. The live timing, being smaller, always loads first in around 5-10 seconds, while the 2d takes around at least 15-30 seconds usually.
Something is causing the 2d screen to not show all of the people in the room, whereas the live timing does.
When someone in the room says something, who is not in the list of people in the room on the 2d screen, 2d locks up!
Here is a pic of it in action. I have replicated it twice. So i do believe this is the cause.
Another interesting thing is the mute button still works on 2d once it locks up, but nothing else is responsive at all.
