A colleague is finding that a page on a server that includes a SWF can load smoothly and be viewed in its entirety, but it generates a JavaScript error message whenever that page is unloaded, but only in IE7 and IE8. (Line 1, Char 1, "Access is denied", Code 0, URL=SWF file name). Firefox 3.6 and IE6 have no problems at all. For some reason, the page has been designed to load the SWF directly into an iframe's src attribute instead of using the usual OBJECT and EMBED tags and associated parameters within a separate HTML page. Is this unloading problem simply IE7 and IE8 being extra-vigilant about security with non-standard code? [more inside]
