I have been playing about with iTunes generated M4A files, correctly tagged.
When I open the files in MP3Tag with the intention of running Case Conversion, individual files take up to a minute to convert with MP3Tag appearing to hang. After a prolonged time, MP3Tag reverts back to normal with the case duly converted.
Here is the error log.
Any help would be wonderful

Can you reproduce the problem with a specific file?
Best regards,

Perhaps I misunderstand but these files are produced using Audiograbber and itunesencode which links directly to iTunes (iTunes v6.0.1.3) where they are encoded with extension m4a.
I have used only id3v1and 1.1 tags
The files play in Foobar and appear to behave normally except when case converting in MP3Tag 2.35 although I have not tried much else.
When "freezing", MP3Tag icons are all greyed out.
I cannot think of anything else
Best,
auldyin
EDIT
Just got this error messsage in Foobar:
Settings\Colin\Desktop\Jeff Healey Band\Hell To Pay\Jeff Healey Band - Hell To Pay - 05 - Let It All Go.m4a" (0)
INFO (CORE) : opening file for playback :

What I mean is, if you can send me one file which I can can use to reproduce the problem?
