For the upcoming MPA2.0 Maintenance Release (MC9500, MC9100, MC55A, MC3190, MC75A) we are seeing an issue on Windows Live Messenger with the latest Microsoft AKU. Issue: if no data connection (WAN or WLAN) exists at the time Windows Live Messenger is started the device hangs.  If a live data connection to the Internet exists then no issue. We would like to know if anyone is aware of any customers using Windows Live Messenger.
