Here is an explanation of how Rev menus work on Mac:
<http://www.hyperactivesw.com/mctutorial/rraboutMenus.html>

Rev will scroll the top of the stack out of view by the height of the 
menubar. What appears to be "0,0" in the topleft corner is really more 
like "0,26" because the top section of the stack is out of view of the 
window frame. The default Rev menu height is 26, so if you set the stack 
to the screenloc you will see about what you describe: 13 pixels shorter 
at the top and another 13 shorter at the bottom.

That's just how it works. When you set a menubar on Mac, the stack is 
visibly (but not really) shorter and its top and bottom edges on screen 
will be less than on Windows. If it is important that the top of the 
stack be at a particular location, then you can do what Jerry described: 
open the stack invisibly and adjust its location on openStack, then show 
it. All system messages are sent normally to stacks that are open invisibly.
