Greetings Nils,
Do you have Norton Antivirus installed? Recent versions of Norton Antivirus added a new
"instant messaging scanning" feature, which can conflict with Messenger and cause it this
behavior. To stop it, open Norton Antivirus (Right-click on the Norton Antivirus icon in the
System Tray/Notification Area (by the clock), choose 'Open Norton Antivirus'), click Options,
then Instant Messenger then uncheck MSN Instant Messenger and click OK.
