Nah, it's also doing it for SHOUTcast streams now, heh, as from today.
[Edit]Yup, it's nothing to do with new versions of software (ie. winamp.exe / 5.1), it's all controlled serverside via the dynamic online media stuff :/ [/Edit]
DrO's already made a gen_diebrowserdie.dll, coming your way very soon (I named it, btw, lol).
Until then, if it bugs you that much, then for now, just tune in via shoutcast.com instead of the media library.
There may even be an option in 5.11 to enable/disable it. Not sure yet though, heh.
ps. btw, I'm moving this from Tech Support to Discussion forum, where hopefully more people will see it, including those responsible ;-)
