Many browsers and also the Flashplayer have access restrictions when running local content.
That means when opening html files directly from the drive in the browser
(visible by 'file://' paths in the browser address bar).
This affects also the local krpano usage - krpano needs to load dynamically xml, js and image files
and this will be locally not possible in these browsers.
To bypass these local access restrictions use a localhost server, e.g. like the
included krpano Testing Server.
