I normally keep around a small library of routines that I call often.  
I'll post them in a following posting.

This is actually very trivial.  Create a UserItem in the Dialog with the
same ItemRect as the default button, and use SetDItem to set it to have
a user item proc of a outline drawing routine.

This is actually a sign of laziness.

You could set your application stack size to be larger at startup.

I guess this is tough to answer.  Once you get the hang of it, it isn't too bad.

Amen.

This may help.

VAR
	thePict : PicHandle;
	PictRect : Rect;
	saneRect : Rect;

BEGIN
	{ standard init stuff like InitGraf, etc etc etc}
	SetRect(saneRect,0,0,screenBits.bounds.right,screenBits.bounds.bottom);
	SetRect(PictRect, 100, 100, 200, 200);
	thePict = OpenPicture(PictRect);
	MoveTo(0, 0);
	LineTo(10, 10);
	...
	ClosePicture;
{set up a normal clip region so DrawPicture doesn't ack}
	ClipRect(saneRect); 
	DrawPicture(thePict, PictRect);

That's right.  There are no magic panaceas.

No - you should LOVE your Mac.  ;-)
