Thanks! Sorry for the crashing - I'm currently digging through as much data as I can find on these problems. Hopefully I can get that up and running again soon, provided it's not some crazy intersection between Unity, DD and browser memory management... Argh.
That said, any chance of emailing your error.log (which is the Unity Webplayer error file) to firstname.lastname@example.org
? That would help me a great deal.
