just came across what appears to be an issue - albeit, not so much with mp3tag as possibly with mp3ext (which quite a few people here appear to use).
anyway, just started finding whenever i'd fix tags with mp3tag, the icon displayed in explorer would then fail to report/show the bitrate (as would previously happen with mp3ext installed).
anyway, not sure if this might be the explanation, but when i changed the tag in options of mp3tag to v2.3 and tried again, all seemed fine.
just wondered if anyone else here had noticed this and had any ideas/thought that mp3ext maybe doesn't support this new tag version - not least as i checked on mp3ext site and there's clearly been no updates in quite some time ..?! x(
ps otherwise, wondered if anyone knew what the benefits of this more recent tag version might be - and if it's worth using at the apparent expense of mp3ext icon handling ..?
