Finally! Together with some problems with iPod Sync this is _the_ most annoying problem I've had with the otherwise excellent MM. Please let me know if you need more tracks for testing...

Andig,

Thanks--I was able to replicate. Tracked at:

Can still replicate in 1251. However, this does not affect all tracks, only some. I've uploaded sample track to http://videodb.net/track.mp3

Please download, change track# (using F2 in track list), refresh folder (F5) -> track# is gone again.

Cant replicate either..

Hm, not replicable here in build 1251.

The issue had previously been posted here http://www.mediamonkey.com/forum/viewtopic.php?f=7&t=33161&p=169538#p169538 the solution using (library node instead of computer node) is not solution.

Problem: mm is apparently unable to edit id3 properties. This has been observed on multiple files.

1) select hd folder, change track# on single file (sofar empty)
2) -> file list is updated with track#
3) refresh folder
4) -> track# is empty again
5) show file properties -> tack# is indeed empty

Debug log (inconclusive): http://videodb.net/mm_tag.log

This is a real annoyance- especially as the problem is not apparent at first. Any chance investigating this (longstanding) issue for 3.1?
