Second load (from cache), of CodeGlass on Safari 3.2.3 does not work.

[Kagetsume]

I see this when trying to view demos at:
http://docs.dojocampus.org/dojox/editor/plugins/ShowBlockNodes

If I clear cache and load it, I can access the demo fine.
if I just reload without clearing cache and access the demo, the spinner stays forever. Or! If I just close and open the demo viewer, I just see the spinner forever You can open and close it repeatedly and it never shows the demo now.

I think your demo loader has a timing issue with onload of the iframe or similar.
