External interface callback breaks differently in different browsers.

egad, got a bunch of hours in on this, and while putting a copy online for this question, found out that chrome and ie work fine, it's just firefox.  anyway, kind of simple, but a pain to explain, but here goes.

javascript-loading SWFs into a div: new one replaces the old one.  using external interface to start/stop SWFs, and get info about their playing status.  made a simple version for this question and i'll throw the link down below.  the problem goes like this:

i load the initial swf.

a button on the page has no problem starting and stopping the swf.

another button on the page replaces the current swf with a new one.

firefox: when you first load the page, you can load SWFs as many times as you want, and wherever you stop, the start/stop button will work fine, but it won't work any more on any loaded SWFs after you use it on the first one.

oddly, i'm finding out more about this as i go along:

chrome: works fine online, but doesn't work at all locally.

ie: works fine both online and locally (sigh)

firefox: does the described problem locally and online.

am i missing something altogether here?  i mean you know, looking for what i need to do for this to work consistently.

if you want to see the problem, i've put the whole thing here:

you can also download all these wonderful files from the page.

thank you thank you thank you anyone who can figure this out.

i'll be happy so blabber more and about this so anyone interested

thanks,
