ExternalInterface / FireFox Issue

Hello everyone, new user to this forum and glad to be part of the Kirupa world.

I hope some of our findings for this issue will also help other people with a similar situation.
We’ve researched and experimented, but still unable to find a solution to this particular issue.

In FireFox is the clickable elements embedded in our flash movie cease to function after 1 click. SWFobject is utilized with “allowScriptAccess”,“sameDomain”, and defined NAME and ID parameters as required by the browsers. Flash Player 9 is installed Flash 8 generates the *.SWF. Our project resides in a frameset environment…Flash in the top frame, and HTML in the bottom frame.

We tested in multiple browsers including FireFox 1.5.0.7 and found everything functioning as intended, except within FireFox. We traced our coding with alerts and tried substituting the External Interface.call with getURL(javascript:function()…), but once the JavaScript function completed, unable to communicate back with Flash. Most of our audience has Flash Player 9 already installed. Currently we are not passing any variables from Flash to JavaScript, just calling the function itself. This morning, we disabled all of our javascript alerts as we have researched this may cause some issues with the *.SWF

Is there a workaround or modification in addition to “getURL…” for this situation, or perhaps a specialized DOM? Appreciate the help and Thanks.
