I can't find anything about this on the boards, so I really hope this hasn't been addressed.
In 0.62a (and every other version I've used) I could have a group of files selected and still right click on a track in that selection and choose 'show file info.' That is gone now. I come across this when using the masstagger; often I have an album selected to be modified by the masstagger, and after starting the process I want to look at the file info for one file to see what info is already there. Now I have to select a single song, and then reselect the whole album if further masstagger action is necessary. Is this a bug?
