Hi Ted,
In ArcGlobe, while in an edit session you cannot access/change layer properties. In addition you are also not allowed to do a manual refresh of the layer (via TOC, rt. click on layer --> refresh) - this is as designed.
Difference in behavior between Scene and Globe is because Globe makes use of a disk cache whereas Scene does not. Changing layer properties will cause a refresh of a layer's disk cache which can cause display issues with edits which have not yet been saved.
So in Globe you will have to define the layer properties before you start the edit session.
Thanks,
