Here are 2 (possible) problems in Think C v3.0 (I won't call them bugs
since they may or may not be):

1) The Debugger.

Every time I interrupt my program to get to the Debugger, it changes
the windowKind field of my program's windows to userKind.

This is a wrong assumption on the Debugger's part, IM-I page 276
states:

	"UserKind represents a window created directly by application
	calls to the Window Manager; for such windows the application can
	in fact set the window class to any value greater than 8 if desired"

I use the windowKind field to differentiate between windows owned by
different modules in my application.  At least they could have
documented this *feature* in the manual!

(I use the window's refCon for other things, so don't tell me to use
it instead)

2) PopUpMenuSelect

I don't know whether this is a bug in the MacTraps library or in the
the Mac II ROMs Menu Manager.

I am writing a MDEF for a popup menu.  When the MDEF gets called with
a message of hPopUpMsg (3), the coordinates of hitPt (top left of
PopUpItem) are passed to the MDEF the wrong way around.  That is, the
right-hand word of the Point contains the vertical coordinate, and the
left-hand word contains the horizontal coordinate.

Could someone please verify these happenings?
