I was visiting Jellystone Park .. clicked on map yellow dot.. and my java console opened with this error.

Revisited page to see if I could repeat the error.. yes I can.  I get error when clicking on Site Map button... map appears and 5 seconds later error is thrown.

I am using IE 7  and Flash 10 viewer.

Not sure what it means:

ArgumentError: Error #2100: The ByteArray parameter in Loader.loadBytes() must have length greater than 0.

(........)How did you limit the cabin scene movement, so you can't pan all the way down?I've never figured out how do get Tourweaver to do an individual scence like that. Good work!   Rob

---------------------------------------

When I need to limit the panning in a scene what I do is to select the scene in the list scene panel and then in the Properties & Action panel I set the propper limit in the Tilt min and max figures. -90 is the minimun down a 90 max up. If you set -45 aprox down it will only pan half the way down. In the jellystone scene I think the people from yogi bear used -50.  Hope this answers.
