Sub-App not showing in Fullscreen?

[Outcast]

I am using the Sub-App object to display another frame in my application. It works as it should as long as I am running in a window, but if I go fullscreen the Sub-App does not show? Why is this? I cant even change into fullscreen or out in the frame I display the sub-app in

Maybe you use HWA (Direct3D) runtime? The sub-app is not show in fullscreen in HWA runtime. But, it show if enable the "Display as sprite" option in sub-app's property.

It seems that Its not interactive if I display it as a sprite though?
