	Actually this is where the problem is.  "CRect myRect" creates an
automatic variable that is on the stack.  When that function returns this
object gets destroyed (you can show this to yourself by putting something
(printf, OutputDebugString, breakpoint) in the destructor and running the
program).
	What you want to do is:
CRect * const myRect=new CRect( <constructor arguments> );
<push the object onto your renderer>
