A basic question.

Example with one model.  When I make a partial selection by click-drag in a sequence viewer , which turns the sequence bright green (in the sequence viewer), 
then ctl-click in the background of the graphics window to deselect, that bright green color in the viewer turns brown, as below.

What does this mean? Why does it do this?  How to restore the original coloring?

When I run the command sequence chain /A, it apparently creates a new instance of the sequence viewer (deleting the old instance). This is OK with just one model.

The problem with this is that if I have several models and do this, it  puts the new instance at the bottom of the other sequence viewer instances, so I have to move it if I want the same physical order as in the Model pane. This becomes annoying fast.

Is there a way to restore the original coloring in the sequence viewer without completely replacing the original instance of the sequence viewer with an new instance, and leaving it where it is (in the case of  several models).

Thank you

Steve
