djsoft said:The red line indicates the mix point, the blue fill indicates the fade out period. They may or may not be at the same point - it depends on the crossfade settings currently in action. I suggest opening a new topic about this where you provide more details, it will be easier to discuss there.
You did mention you had a bug with short files.
I will wait until 5.8.0.4 comes out and see what happens in there.
