As firstname.lastname@example.org wrote on the ML in July 2018:
"when rescaling, the view is set on the top traces regardless of where I was looking earlier. I also notice that moving a trace is a little difficult when I go beyond the farthest down one, seen from the top. If I grab a trace far down, the window is immediately moved to showing the top traces and I can only drop the trace there - I can't move it further down. In the analyser I have 32 channels, but only the top 15 (approx) are simple to view. The other ones can of course be viewed, but I need to rescale and then move the window down. I'm also careful not to grab these as they then drop at the top and I can't move them down."
So there appear to be at least two issues here:
1) scaling changes the view to show the top traces
2) moving a trace changes the view to show the top traces
