After you edit the cue points of a track, you can save them to the ID3 tag. So even if you import that file on another computer, or you loose the database and start from a blank one, you will not need to edit the cue points again, but for an unknown reason on some tracks it just hangs instead of skipping them.
The problem is that i didn't succeeded to replicate that behavior to fix it. I still hope that a user will identify a track that makes that and send it to me to test it.
