Topic: SWFupload broken

I've just found out this morning.  I think it might have been the latest version of firefox and IE, but I tried the demo page and it was broken there too.  From firebug, it seems to throw:

uncaught exception: Error calling method on NPObject! [plugin exception: Error in Actionscript. Use a try/catch block to find error.].
[Break on this error] xajax.ext.SWFupload.forms[form_id];}

I had this working on my site at least 2 weeks ago but now no more.
Anyone run into this error?
