	I dunno, you could try:

	(A) SetAPen(Rp, pen)	(maybe your flooding the same color as the
				background?)

	(B) Setup an AreaInfo for your rastport

	I'm not sure whether you need the AreaInfo structure or not for
	Flood Fills, but it's the only thing I can think of that could
	possibly be wrong.  You probably have already discounted (A).

	Also, if you are using Manx and not Lattice, make sure the variables
	in the calling arguments are the right type (short/long, whichever
	the manual says).
