After the 2.7 update, in the right hand window where Picard shows the results of the album look ups, after hitting save the various icons don't update to show that the tracks have been saved/the album has been saved.  The coloured rectangles for tracks don't change to check marks and the gold albums don't lose the purple asterix. 

The tracks are being saved as evidenced by the progress counter at the bottom of the program counting down and if after the operation is completed I remove the album from Picard and then put it back it, the program does recognize it as having been tagged.  The visual in progress indicators are just broken after the 2.7 update.

The attached screenshot is of an album I just hit Save on.  Picard successfully tagged the files but I didn't get any of the visual indicators that the operations completed like I did in 2.6.
