DeltaV Live Display Frames Co-ordination


I am trying to figure out an issue related to display frames co-ordination. In DV Live I am using dual monitor layout and each display has used two display frames, one for L2/L3 and the other for L4, L4 usually opens on the same display where we open its L3. Now here comes the problem when I am enabling the navigation bar on each L2/L3 display frames then at run time both displays are opening the same L2/L3 graphics. I have tried by enabling the ‘Prevent External Co-ordination’ check box, it has disconnected the both displays auto co-ordination but now L4s are opening on L2/L3 space. So I am not sure how to handle this problem in Live. Thanks in advance.
