I have noticed that when I use MP3 tag to edit / add tags to FLAC files, the file modification date (as displayed in the windows file system) does not get updated to show a change has been made. I have tried tagging MP4 and MP3 files and the modification date does get updated correctly there, and i don't have the "preserve timestamps" option checked. It's causing me a problem as the files get backed up over a network, and if the mod date does not change the files do not get copied (unless i use hash key checking which takes forever).
Thanks.
Howard.
