Ok, you could say, problem gone all fine but I think if this happens it can happen again. And you know the user, doesn't work? Bad!
sorry, without more informations I can't say much...
maybe an loading problem? do you know if there were errors?
what krpano version was used?
maybe use the latest krpano.swf from the 1.0.8 beta 9 tools package,
there an automatic loading retry is included,
this retries to download a file again when the server was busy...
best regards,
Klaus
