Please change the behaviour foobar manage files with id3v1 tags after mp3gain added it's tags.
The problem is covered here. (http://www.hydrogenaudio.org/show.php/showtopic/13569)
why do you open another thread then, if you know that there's an active thread already?
Breaking the nettiquette (and maybe board rules too, dont know for sure) won't improve the chances of this bug to be fixed for sure.
This thread is unneccesary.
EDIT: oh, and BTW, you're posting in the wrong forum too, although you obviously know the support-forum already since you startet the original thread there.
