Hello,

I am changing album art simultaneously for all files in a folder (same album), using "Edit ID-Tag for multiple files".
There is no issue when files are in WAV format.

But some troubles occure when files are in WMA format (lossless): randomly, about 1 of 10 of the files remain unchanged.
When I come back to those files individually with "Edit ID-tag", it works.

I observed this about 100 times now.

Best regards.
