Ok i booted up my XP box earlier and everything loaded up fine like it should, anyhow i go to close MSN messenger and i keep on getting this error.

There are other applications currently using features provided by Windows Messenger. You must close these other application before you can exit windows messenger. These applications may include Outlook, Outlook Express, MSN Explorer, and Internet Explorer.
But the funny thing is that i don't have any of these programs/ Applications running..
So i am finding it hard to work out what making this happen..
I've updated nortan and ran a full system scan, run adaware and spybot. And ran the cleaner as well, and they all came up clear so i've eliminated that it's nothing evil..

I've also tried using spybot's tools to disable it from starting up at startup but with no success so now i'm just clutching straw to figure out what's up with this.

So does anyone have any ideas on what this might be, or how to stop it.?. cause i'd sure like to know.

Anyhow Screen shot attached..
