A minor issue.
The coverart that is displayed for the folder when there is a coverart.jpg in the folder is displayed differently in Dopus 13 than it was in DOpus 12.
I think that in DOpus 12 the image is fitted to the 'CD overlay' with the aspect ratio ignored and in Dopus 13 the image is displayed with the aspect ratio intact, causing some of the image to disappear.
Is this a bug and if not, is there a setting to get the same behavior as in Dopus 12?
