Hello Erikywillian

Use a string instead the "basescreen" selection like this:

hen it should have also the effect that the screen is opened in the main Screen Window.

(I would suggest no to change the main screen window. perhaps you should use another layer with a amin screen that do not change and then you use a Screen window inside it to change the content. This would be more flexible)

Hi Erikywillian,

I suspect your problem stems from how you open the pop-up.

The OpenScreenInPopup system function has an optional parameter for the parent screen. If you don't define a parent screen, the pop-up window opens globally and independently of any other screen. In this case, using the base screen for the ChangeScreen system function will not work.

However, you can specify the full path, which allows you to work without a parent screen for the OpenScreenInPopup system function. But, in this case, the pop-up will remain visible when the screen changes.

Kind regards
Stefan
