How to create a non-blocking popup page?

It sounds strange, I searched for the similar topics for modal popup and popup. As I understund with common sense, modal popup is blocking, popup is non-blocking. But all my popup pages, no matter of modal and not modal, are all blocking. That means, I am not able to get the background to open another popup pages. Whats wrong I did here? Even I created my own layout with popup, not modal, but it is still blocking, I am not able to get the background page without closing the popup page. How to get a non-blocking page in mendix?

Hi Wenrong, did you also select your non-modal popup layout for your page?
