Bug? Immersive mode showing bars when user clicks on a b4xcombobox control

When the program is in immersive mode I am finding that clicking the b4xcombox controls brings the top and bottom bars back into view as shown below:



Is there a way to stop this happening?

This device is a tablet rather than a phone.

Immersive mode, which is a native feature, is built for games. I guess that the overlay menu causes the bars to reappear. It can also happen when the keyboard becomes visible.

Try to call Activity_WindowFocusChanged (True) after the user selects an option.

If you want to prevent the user from switching to other apps then you should make it a kiosk app: Device Owner / TaskLock / Kiosk apps 2017
