Hi Jens,
I've tried your plugin on my futur WP website actually under construction on my computer.
I've tried two option to visualized my panos:
one with shadowbox, who is calling an URL (html file: http://www.didier-oberson.ch/panoramas/2009…chey/index.html), second is your WP plugin who's calling the swf file.
First works well, WP krpano not.
I've a message of "loading error - Security Error".
Like others, I'm working with Autopano Giga+Tour, with krpano license.
