Hi,

It looks like your changes _should_ work, according to the Adobe docs. 
The fact that sniffing the connection shows nothing indicated the client 
isn't sending anything.  Have your tried sending a simple String or 
other parameter when calling connect()?

It's possible connect() is being called from elsewhere.  You could try 
running in backtrace mode by checking 'backtrace' in the developer's 
console.  Next, click on the debugger message(s) to see the full backtrace.

Sometimes, running the Flash debug player can help catch certain kinds 
of exceptions: http://www.adobe.com/support/flashplayer/downloads.html

Let me know what happens!
