I changed the volume for part of a measure on one track and stored the resulting file. I reloaded the file later and I can see the boundaries of the previous change as thin vertical lines on the track. There is no UNDO available from the Edit menu, so the change appears to be permanent. Now, if I want to make another change to the same region, and I fail to line up the boundaries exactly the same (yeah, like THAT's gonna happen!) the second change frequently results in a click at a boundary.

Okay. I understand what the vertical lines represent from the previous change. My question is: If I can't do anything with those boundaries after a reload, why are they still in existence? Seems like an annoyance with no benefit.

Thanks.
