Creo 4 relations not returning to last edited position when using Look In

I am using the new relation editor not notepad.

When I finish editing relations I then exit the editor by selecting OK, I am pleased to find that upon returning to the editor the cursor location is at the same location where the relations were last edited. 

Here is the problem; when I edit relations of a child of the parent assembly by using the 'Look In' option I am disappointed to find that I am returned, not to the last edited line of the relations, but rather the very bottom of the relations. 

Is this is a new feature of 4.0. 

What can I do to fix this?
