Hi there. I don't have this program (and I'm sure that those who do just haven't seen your posts yet) but I did some web searching and found this response to a similar problem:
If that makes sense to what you're trying to do, why don't you try it and see if that helps. If not, just reply back... I'm sure between all of us we can help you figure this out.you may have the Toggle Overlay Tags "on". That would color every object on that overlay a single color and I believe the default is dark blue for the Design overlay which is the default "first" layer. The Toggle Overlay Tag button should be on your left and kind of looks like the corner of a ziggurat with each level a different shade of blue. Try clicking on that and see what happens.
