Help Creating a Floating Window

I'm trying to create a window that floats on the UIQ's phone screen.  I can create the window, but it disappears when the app goes into the background (not surprising).  

In HandleForegroundEventL, I set the ordinal value of the window:

     iToolbarAppView->ViewWindow().SetOrdinalPosition(0, ECoeWinPriorityAlwaysAtFront+10);

but the app still disappears.  When I set the RootWin, like

   iEikonEnv->RootWin().SetOrdinalPosition(0);

then the window and it's menubar, etc, do indeed remain on top, hiding other apps.

So I'm confused.  How do I set a floating window to always stay on top?

Thanks.
