Years ago, I created a swf that upon init, loads an external swf. It worked reliably for years. Now, it's been brought back, but no longer loads the swf in more modern browsers, like in its heyday. It now fails in Chrome 57 and IE11, but worked around IE8 and Chrome 20ish. I'm thinking this might be a security issue. I tried setting compatibility mode in IE but that didn't help. Am I missing a security setting somewhere?
