I have been trying everything I can find to have code start on the window.onload event that uses callbacks exposed via the ExternalInterface. I've had many of the attempts working in IE, but Firefox is causing me grief.
Please let me know if you have any suggestions. The only other thing I can think of at the moment is using the swfObject for writing the flash tags to the page, but I'm already writing them from an external file (and removing the IE "Click to activate this control" issue in the process). All these methods work fine after the initial load (although I also had issues with Firefox when I simply try to call the onload instructions after a setTimeout command as well).
Thanks for your help.
