Graphics Not Clickable in 1 Screen of a 3 screen Workplace

Hello,

I have a 3 Screen Workplace..

Screen 1 Configured for Displaying - Alarm and Event List

Screen 2 Configured for Displaying - Graphics

Screen 3 Configured for Displaying - Trends

Now, when I open a Graphics from Screen 2 as pop up and place it in Screen 3.. I am able to Click and open Faceplates and navigate through navigations buttons..

The same works in Screen 2 as well...

But when I move that graphics to Screen 1, I am unable to click anything on the graphics.. It became unclickable..

I tried different graphics. But all showed same result..

This is the issue faced by me.. Pls let me know the solution and reason for this behaviour...

Thanks in Advance..
