Hi  
I am not sure if this is a bug or not.  
I am using mp3tag v2.58.  
and editing flac files thru the extended tags.  
I will select a group of files to edit.  
right click and select extended tags.  
If I select only one file that has the tag / comment of RippedBy its value of XXX  
and I change it to EncodedBy its value XXX it will perform the change.  
But if numerous files have RippedBy and different values and I change  
it to EncodedBy it deletes the RippedBy and doesn't write the new EncodedBy.  
Note there are no new comments added at all.

Thanks  
frazld

In dialog "Extended Tags...", you have detected a known limitation when changing the content of a tag-field's key.  
Renaming a tag-field's key will work only on one file.  
If more files have been selected, then this tag-field within all the selected files will be removed.  
Immediately pressing [Ctrl+Z] may restore the tag-fields.

The recommended workaround is ... do a two-step process:

1. Action "Format value" to copy existing values from the old key to the new key.
2. Remove the old key.

Well, me too, I would like to see this limitation to be gone.
