Shoutbox

Ok
I am on msn doing my thing and all of a sudden "new msn available"

so I am like what can be so bad?

Well for some reason it won't stop freezing on me.
I am talking to someone, switch to read something on a browser(mozilla if it matters) and it freezes
I am no doing anything about to write my reply after reading and my cursor doesn't show up in the msn box

any help would be appreciated

thanks
