No problem Mark. I just didn't want you to keep having to start blank maps. Is there a reason why you're going through this 'convert to graphics' workflow rather than just hitting the Mask button on the Image Analysis Window? I mentioned this method well before Jeff S. replied to you -technically it was even before you posted the question. Maybe you didn't read the whole thread. You can also Clip with the Image Analysis window - all you need to do for both is select a polygon from your feature class. No conversion to graphics required.
