i have noticed that the app does not remove itself properly from memory when either the close window button or file / exit menu item are used. I came across this when I had exited the program and found a MP3Tag folder in my TEMP directory. i tried to delete the folder and couldn't. i brought up the Task list and chose the prcesses view. The MP3Tag .exe was still running. i could then kill it and thus release the directory for deletion.
the program does not consume much ram but i would prefer if the application exited when I told it to do so.
