Thanks to all the people who replied, and enough already!  The answers
I received suggested two approaches.  One was to set thePort to DeskPort,
as documented in IM I.  Unfortunately, I can't find DeskPort in the index of my
copy of Inside Macintosh, nor is it defined in any of the obvious .h
files in Think C 3.0, so I can't comment on this approach.  The second 
suggestion was to change the *clipRgn* of thePort.  Apparently, 
NewWindow sets the clipRgn of the WMgrPort to the structure 
region of the newborn window.  Set the clipRgn to screenBits.bounds, 
and you can tromp all over the complement of the menu bar at will.

Thanks again to those who responded.
