within 0.92g (i dunno about the latest versions) there is an evil bug within the tagging! when id3-tagging non-tagged files, the last 128 bytes of the file will be overwritten, which will lead to an "out of sync"-error or even a crash of the plugin. in this case the end of the file is destroyed - i killed about 2 dozen of my own files :/
will be fixed in the next versions...
sorry,
andree
