I'm not sure why you are doing an OpenPic.  Try the following (trust me, my
code *always* works):

	Rect	destRec;
	Handle	myRes;
	unsigned long	resname;
 
    ClipRect(destRec);    /* you need this I think */
    resname = 'PICT';     /* Stuff the res type into 4 bytes */
					/* you may need to make this hex, then stuff it in */
    myRes = GetResource((ResType)resname, ID);

	DrawPicture((PicHandle) myRes);

And away you should go.  This may be totally wrong of course, but I don't want
to try this under LSC with MulitFinder.
