Confirmation Window Popup loaction

I have an application in Edge 7.9.10 where I have multiple screens which are called up at launch using the startup script method. Each screen is independent on the extended desktop. All is well there, works like a champ…until you press a button with confirmation used. The popup that is created by the button confirmation always goes to the primary monitor regardless of which of the 3 screens the button was actuated from. Is there a way to direct the confirmation popup to a specific screen? Or is this a Java/Windows limitation and it will only go to the primary screen?
