open url or file - project moves to next screen?

Hello,

When a user clicks a Click Box to open a PDF file, the PDF file opens correctly BUT, the project itself automatically moves to the next screen. So that when the user closes the PDF, the project has moved for example from screen 9 to screen 10 (the user is confused because they are now on a different screen from which they departed.)

   Already tried:

     1 - Adding an extra Click Box set to "Pause until user click"

     2 - "Continue Playing the project" check box is deselected.

How do I stay on the same project screen while opening a URL file in a new window.

Thank You.
