You check that the top left corner is within GetGrayRgn ( ).

Try:

	Rect * * thePos ;
	RgnHandle theFoo ;

/* Read in the saved rect */
	thePos = ( Rect * * ) GetResource ( 'Rect' , 128 ) ;

/* Construct the screen outline minus a little slop in the
   lower right parts */
	theFoo = GetGrayRgn ( ) ;
	HandToHand ( theFoo ) ;
	InsetRgn ( theFoo , 5 , 5 ) ;
	OffsetRgn ( theFoo , -5 , -5 ) ;

/* Check for sanity */
	if ( PtInRgn ( * ( Point * ) * theRect , theFoo ) ) {
		/* Use * * theRect */
	} else {
		/* Use your default - screenBits . bounds maybe.
		   GrayRgn . rgnbBBox covers _all_ screens, and thus
		   is less optimal ;-) */
	}

/* Be nice to memory */
	DisposHandle ( theFoo ) ;
	ReleaseResource ( theRect ) ;

Happy hacking,
