Bruce STEERS reported a new bug.

Summary
-------

Form.AutoResize and top level menu error (GTK)

Type             : Bug
Priority         : Low
Gambas version   : Master
Product          : GUI components


Description
-----------

On the attached app i'm getting this weird behaviour on GTK but not QT.

If the TopLevel menu is visible and From.Autoresize is enabled the Form.Height shrinks to zero on load.

If auto resize is disabled it doesn't do it
if top level menu is hidden it doesn't do it

And none of my other apps seem to do it just this one?
