	I haven't given it too much thought, but here goes:
	When doing window updating in this fashion, QuickDraw will
only draw your picture upon *updates*.  You said this is a
startup screen so undoubtably MyWindPtr is the only window on
the screen.  If your window is displayed at the time of
GetNewWindow(), it has no reason to do an update when you call
ShowWindow().  Go back to the WIND resource in ResEdit and
set its visible bit to FALSE.  Maybe it will work then.

	First, you should set the port before drawing, just to
make sure, with the call SetPort(MyWindPtr).  Also, the rect
SomeRect is not guaranteed to have a topleft corner of (0,0)
so it may be off the edge of your window.  Before
DrawPicture(MyPicHdl,&SomeRect) (note the syntax), say
OffsetRect(&SomeRect,-SomeRect.left,-SomeRect.top).

	For both of these techniques it is handy to call
DetachResource(MyPicHdl) right after reading it from disk so
that the Handle points to a picture, and not a resource.

	I hope this solves the problem.
