I need to monitor NewWindow.
 
MultiFinder seems to be patching NewWindow and *replacing* it. Thus, a patch I
install at INIT time never gets called.
 
A patch to NewWindow I install at the time of the first GetNextEvent affects
only the Finder (or the startup application) even if my patch code lives in
the System Heap.
 
I patched OpenResFile and waited for something other than MultiFinder to be
opened. But by that time, MF has monkeyed with SetTrapAddress enough that the
trap dispatcher gets confused and blows up.
 
Anybody got any secrets about patching after MultiFinder?
