JSONP Polling sends message twice

[vti]

I cloned the latest Socket.IO.node, started an example chat application. Opened two tabs in Firefox 3.6.14 and sent a message. On the receiving side I received the same message twice. I've noticed this only when using 'jsonp-polling' transport. Other transports work fine.

Please let me know what additional information would be useful for you.

Firefox should never use jsonp-polling.

Ok, thanks :)
