This may be a bug, or a feature, or a lack of intelligence on my part. I work on Win10(18362), and Mp3tag v3.01. I used Mp3tag many years ago, now starting again.
I have several self-made mte-files, e.g. c:\Users\user1\AppData\Roaming\Mp3tag\export\txt_taglist_length.mte. I can modify those, and it works, no problem.
But I expected that I could also edit them through Mp3tag. What I do:
Actions --> edit one of the existing Action groups --> Edit an action, in this case: Export "txt_taglist_length" --> it shows the Export configurations. I select "txt_taglist_length" and click on Edit.......
What I expected was that I could edit my mte-file here.
What happens is this:
- for a fraction of a second a message window pops up, too fast for reading
- the main Mp3tag window, in the background, loses all its mp3-files, becomes empty.
- the export config window regains focus, so no edit window
Could it be that I need to give administrator rights somewhere?
