Popup is a non-modal window and it closes self by any user’s actions outside of popup. Use “window” if you need some UI that will be constantly visible.

@maksim I understand, But just try resize the popup in chrome/Firefox it still stays visible. As i believe somehow IE is firing click event somewhere in flow automatically due to which leads to hide event. Whereas in Chrome/Firefox it never happens.

FYI i need popup window for some reason.
