This is what I get: Homepage menu is visible however Print button is pressed and everything is unresponsive at that moment. After about ten seconds the page opened and everything went normal again.
And about the upnp thing. I checked Messenger Options>Connection and it says "You are connected to the Internet via a NAT restricted with UPnP connection point". (sorry for the translation mistakes) Maybe that is why my two computers (laptop and desktop) experiences this because both are connected to the same adsl modem.
