Bob and Robert,
Make sure there are not any projected views related tothe view you are trying to section and unfold. They will cause the unfold option to be grayed out. If you do have projected views off of your sectioned view, change them to general views, instead of projection. This should allow the unfold option. This applies to WF 3, and I would also assume WF 2, asRobert's description sounds the same. There may be another trick to do this, but changing projected views to general is the only way I know of.
You are the best, Inick. Thank you!
