Windows Messenger Shut Down Problem.

Hello.

When I close Windows Messenger, it goes down to the system tray by the clock, then when I right click the icon there & select 'Exit', I get the message, "There are other applications currently using features provided by Windows Messenger. You must close these other applications before you can exit Windows Messenger. These applications may include Outlook, Outlook Express, MSN Explorer & Internet Explorer."

Non of the applications mentioned are running, & I can not close Windows Messenger down out of the systyem tray.

Any help on this matter would be appreciated.

Thank you.

 

I should have said that I am running Windows XP Home edition!
