Hi Jim, If you use 'show on a face, it shouldn't force a refresh of the parent face. Have you tried that? It can be a bit tricky if the face you want to refresh is a large one. REBOL slows down a bit when refreshing large faces. You can get really good response times, though, when refreshing lots of smaller faces that sit on a larger face. Cyphre has some great examples of that technique.
