I don't know if this is a bug or just a limitation of the program or my system. I am running windows 10 (Up to date).
I am using the latest version (3.08) of MP3TAG and am having a problem with a simple action I have created. (Format value "COMMENT":$left(%albumartist%,1)%albumartist%) The action works fine on small quantities of MP3 files, say 100 or less, however, if I select a larger quantity say over 200 The action runs until it hits around 120 to 125 files and then hangs. I then have to terminate the program using Task Manager and sometimes force a reboot.
