Only thing I can think of right now would be to load your buttons with visible="false" and use something like onxmlcomplete to initiate an action where the buttons are turned on (visible="true"). Look at the release notes (in the download package) for possible Events.

OK, one more...
You could also get fancy and initially set them all visible but with an alpha of zero (transparent) and then use an action to tween the alpha to 1... and play with tweening a group of them... followed by a wait... then tween some others.

There are probably other options... but just remember that you can separate the "loading" of the plugin and it's visibility to achieve various effects.

Hi,

Quoted from "Rahim"

is there a way to time the preload so that some things load together

no, the preloading can't be timed,
but the pano itself will not start or do anything before not all elements with preload="true" were loaded,

best regards,
Klaus

In my tour size of elements marked preload="true" above 2Mb..

preload="true" on your progess bar?

Yes, But the progress bar is shown when the preview starts to be loaded.
