BPM and Key tags not written to file (windows)

Hi,

I have noticed that BPM and Key tags are not written to the actual file. I have tested this with FLAC and MP3 files and opened the files in MP3Tag (Windows) to verify this.

The BPM and Key tags are set after RB analysis and the 'Write value to the ID3 tag' option is enabled. MyTag values are written to the Comment tag, so some updating of the actual file is taking place.

Does anyone know what is going on here?

Thanks,
Paulo
