It happens to me very often, so I'd learned not to do point 6. too early.

I can enforce it:

1. Start a track of an album to play
2. Open View>Properties
3. Select all tracks of the Album
4. Assign an Album Art
5. click "Update"
6. [b]Immediately[/b] click an other track in the Main List to play or tag.

--> in about 2 of 10 cases the actual track starts looping (12 sec. on my PC).
Tagging of the remaining tracks is very slow.
Sometimes tagging freezes and MM (still playing) must be killed via Taskmanager, that may end with an instant "brrrrrrrr" of the SoundCard -->reboot.

EDIT: It also happens, when I tag only one track. Bug report windows flickers continuously and doesn't accept the "Send" action :cry:

I can't reproduce this. If you can generate a debug log, that would be helpful.

Thx.

MM locks for around 3 minutes after clicking OK from the "Edit Properties for Multiple Tracks" dialog, after changing the AlbumArtist and Genre fields of 360 files.

Meanwhile, MM continues to repeatedly play a small loop of the currently playing track.
