can you explain this in further detail, because is it your z order, your layout order, or your layer order. the z order just makes it so that in one layer you can change which items are on the top and on the bottom, so lets say i had 2 objects on the same layer and obj 1 goes behind obj 2, in the z order i can change it so that obj 2 goes behind obj 1, but if they are on separate layers than which ever layer is on top will always be on top. i'd need to see an example of what you're talking about.
