I'm reasonably sure this is a Safari issue of some kind, I've got the debugging Flash plugin and things show up perfectly in Firefox, but in Safari I get no avatar images while trying to customize my avatar to enter the world. Trying to just skip past the customization screens and go directly in gives me a page with a spinner forever, or ten minutes or so anyway. This appears reproducible between browser restarts. Installing the debugging plugin didn't change the behavior, is there information I can pull from that plugin that would be useful?
