How do I get Twitter to not lock up my game when I use it?

Hi there,

I've got twitter working in one of my games in my testing, but each time it pops up a popup, the game itself seems to have frozen. I can click buttons and hear sound, but other than that, they don't reset layout or change scenes.. any idea what could be going on?

it doesn't matter if i successfully post or just close the popup.. same locked up result

Thanks,

Caleb
