Who to recreate:
1. Make sure Firefox (or chrome?) is set as your default browser (instructions: http://superuser.com/questions/144228/h ... eb-browser).
2. Open the Auto tag from web... (Ctrl-L) window for some album.
3. Click on some link or the cover art image.
IE is launched, not the default browser of your choice.
p.s.: If you right click and select entries from the Get info/buy... menu, the default browser is launched.
