Tags not synchronising

[oceanclub]

Hi,

Am running the latest beta 4.1.6.1728. I can see I can update a song's info in MM, then apply Advanced Tag Management -> Synchronise Tags. But when I then check in Windows Explorer, no tags for the track are shown.

What file type (as Windows Explorer doesn't support this for all file types)? Also could the files be read-only?
