Its been a while since I used Mp3tag. I updated to version 3.05. When trying to move mp3 + cdg pairs mp3tag only moves the mp3. I recall this being one of my most used feature in previous versions. Can you please enable this feature back. If my memory is correct about 2+ year ago in a previous release this feature was disabled and after opening a bug report, it was enabled back on the next release.
Thanks in advance
