All appear to transfer in the usual manner, window opens up, green line indicates transferring. Regarding the "Cue Sheet" reply, that's interesting because i've noticed that the problem files show a small cue sheet option in musicbee whilst those that are fine don't. I've never really understood what that means or how i go about solving the issue in this regard? Think you've probably hit upon something, if it's an easy fix a detailed explanation would be greatly appreciated. Thanks!
