HELP!: Does Flash Cache Data by Default?

Hey Friends, does flash cache images and text loaded in AS3 by default? The code does not have any LSO’s or any other read write senarios in it.

 Just supposed to load the flash app when the page is loaded, and re-load again clean when reloaded.

 But I noticed today that the images were not completely loading in FF5/Win Chrome/Win but did in IE8. I cleaned out the cache on these web browsers and everything seemed to be OK again. But I need to trust the user wont find an issue.

 Is there html or as3 code I should use prevent the possibility of it caching?

Any help is greatly appreciated. Here is a link to the beta page: http://bit.ly/qD75hr
