Middle-Joypad-button. It's not too much of a problem - Just something you might want to look at, not least of all as it gives yet another button to map!?
I didn't try the rest of The Dig with the new build (Went back to the stuttering old one to complete the game) but I'll try it when you get another one out to fix it.
Just testing SamnMax (Full talky with Ogg audio), Indy Fate of Atlantis (Full talky with Ogg audio) and MI2 with the current release - Will see how they fair.
