Melodyne 5 Studio upgrade from Editor

Very nice, but ran into two issues

Love Melodyne products, but have 2 problems: 1) stand-alone works ok, but always gets vague error on exit ... Melodyne says it's my computer, 2) some features don't work right in Cakewalk ... when "comping", blobs unfortunately show even for muted clips (I suspect this is a Cakewalk problem).
