I'm noticing that Vegas doesn't always fade audio crossings at clip ends/starts. Definitely this happens when audio is ungrouped from its associated video clip, but it also seems to be happening intermitently with clips in general, maybe when there is some specific kind of fade or drag move.

I never really noticed this until I started hearing clicks. Close zooming revealed that the clip ends didn't have the normal fade in/out envelope. Yes, I've got the quickfade option enabled. It just doesn't seem to work with 100% consistency. V10e.
