OSX FullScreen (Again!)

I’ve read the forums on this for which there are several posts, but still cant get it to work.

Using Xojo 2016 r1, OSX El Capitan (10.11.5), Apple Cinema Display (2560 x 1440).

When I run my app, if I click on the green maximize/fullscreen, its goes fullscreen as expected.

If I set Window1.FullScreen = True in the app, when launched, the toolbar in the app completely disappears and the apple menubar remains visible. Its almost like the top section of the app is hiding behind the apple menubar. It looks a mess.

The result is the same when setting the FullScreen option in either the Open or Activate events of Window1.

Is there a way to get this to work properly ?
