Avoid to create repeated XUI dialogs

Hello Guys!

So I'm working on the creation of an XUI dialog in Arbortext Editor, what I would like to know is if there's a way to avoid to create the dialog twice. The way how I create the dialog is creating a new option in the menus bar and from there I call the script to create the window. I have another window and I'm using a global variable to store its ID so I can validate if the window is active or don't, however I think I can improve that method.

Any ideas?

In advance I appreciate so much your time!
