I'm also having the same issues... very frustrating and not an issue I have had with other editing software.

If you drag the Audio past the vision after you have detached, you should then be able to delete the vision and the Audio should remain. Good luck.

I'm having the same problem as Ami. If I get a video and separate audio (for sound quality), to line up, it's totally by luck or a lot of frustrating back and forth adjustment. Please help.
