Flash websockets failing with Flash 11.8.800 - works with 11.6 - on IE8

[SockToy]

Weird. Works on first page load. Does not work on page refresh at same URL, or page load on other pages under same domain. Works on page load under different domain.

i.e.

http://DOMAIN:3000/Page works on load one
Hit refresh
Fails with object expected at setCallerURL
Fails for http://DOMAIN:3000/Page2

Works for
http://DOMAIN:3001/Page for one try, fails for second

Works fine if I totally close down browser & restart, for one pageload only.

Failure line is always
WebSocket.__flash.setCallerUrl(location.href);#
in WebSocket.__onFlashInitialized

Failure message in IE dev tools is 'Object Expected'
location.href is set and valid, websocket & flash.setCaller are both defined, arguments are identical between success (first load) and throwing an error (second load).

Page works fine in Firefox with native websockets

Error throws before any debug output with the various debug vars set on.

Server is mojolicious, with an appropriate flash security file being fed out.

ideas?

Appears to be a flash 11.8 specific thing, tried upgrading to 11.9 and works. Any thoughts on workarounds for users with 8 installed? ('Upgrade to 9!') ;-p

Hmm I have no idea about the workaround.
