Halo 2 campaign co-op Bug

Whenever either of us presses tab during a cut scene (even just to switch the graphics) it ends the game there and ejects both from the party. Has anyone else experienced this? Is this a bug or am I screwing something up?

When I was playing co-op with a friend (I’m in the UK, he’s in the US), we would have to skip the cutscenes immediately or risk the game kicking us out of the session with Halo 2. It was weird. Might be related. Halo 2 seems to be the buggiest when it comes to co-op stability.

Interesting, I didn’t think that it would have such stability issues after the flight earlier in the year. Anyone else having odd stability issues then? maybe this bug isn’t as specific as I initially though lol
