Firefox reloads SWF file on resize & loses context

Question

I have a Flex application. I use SWFObject (v 1.4) to "add it" onto the web page. When the webpage loads, Javascript is used to initialize some variable in the Flex app. Then the Flex app loads some images and displays it to the user.

With Firefox, after everything has been loaded, when I resize the browser, the Flex app is reloaded. I see the default "Loading..." label and the Flex app loses the images it had loaded and becomes blank. How can I prevent this from happening?

This does not happen in IE or in Google Chrome.

Thanks.
