Allright, "Dive In" is working again, but it still doesn't look very good at all and the button to bring you back out to the Bing Map, is without lable. It's just white, so as to be confusing and useless to general public browsing..
Ahh remember when photosynth first came out in 2008 and IT WAS PERFEcT!? It displayed in Direct 3d by default, and you could browse from synth to synth within 3 clicks. It was a luxury user experience for a few months. Damnit.
