IE7&8 on XP does not work with the chat example

This worked fine with current version of socket.io-node & node 0.1.102, but is broken when using current stable version of node (0.2.4).

Simply hangs on connecting and raises socket.io.js error on this._iframe

Not an issue. This only happens when using xp in virtual machines.
