[X] Drag & Drop to external Software removes files from list-view

I don't believe this behaviour is an intended feature: If you drag & drop a files from Mp3Tag to some externel software (i.e. Audacity, Mp3 Quality Modifier) these files vanish from the list-view-frame. You have to refresh the view to get them back again.

Maybe there are german explanations, which can help to understand Drag, DragCopy, Drop and the usage of the related keyboard shortcuts ...
