Great. I wouldn't say cross purposes, because as I said the contents of the menus are the same. When you use the file list view type, the one pane you get basically IS that bottom pane; it doesn't display categories up above, instead it just shows the file list, which is normally in the bottom pane. I didn't expect you to see your field right away, because you were using a custom field. I expected you to explore the More submenu, and you'd find it there. No one would know the name of the field except you, because you created a custom field, but I knew you'd know it when you saw it. You just needed to look in the right place.
Glad to help... Have fun!
