I've learned to work with it, though I do wish it were fixed. There's a 
conflict if you have destroystack set to true; if you don't set that 
property then chances are the problem will go away.

But there are a few tricks to get around the bug anyway.

Set the minHeight while "Set as Menu Bar on Mac OS" is turned on and it 
will always be accurate on any platform. This is the only time during 
development you should have that checkbox ticked.

Always use the card height, not the stack height. The stack height is 
equivalent to the window height, which will indeed be shorter on a Mac 
when there's a menu bar (because the card has scrolled up so the window 
is shorter.) The card height is always stable, even though the top few 
pixels may not be showing.

The size of the window will change if you toggle the menubar property, 
so don't do that. If you want to hide the menubar, just use "hide 
menubar". Don't change the window size by removing the menubar entirely.

Set the editMenus to true during development (turn off "show as menubar" 
on a Mac) and place your objects that way. In fact, during development, 
always leave the menubar as a visible group at the top. Don't set it as 
the system menu bar until you are all done with the stack. In fact, I 
leave it as a group all the time and I build for both Windows and Mac 
without any menubar set. Then in a preOpenStack handler I do this:

  if the platform is MacOS then
    set the menubar of this stack to "myMenuBar"
  end if

That way the standalone builder is happy, controls all pop into place 
correctly, there's no extra space or truncated space when the stack 
starts, and basically all is well.

You could try just turning off destroystack though, and the problem may 
not happen at all.
