I just tried it with mine and it seems to be working. Be sure that you are hitting "Save Folders" at the bottom of the Edit Folders screen. After doing so I can see the custom folders in both the "jump to folder" combo and in the "move to folder" list.

Note that you need to select your messages via the check boxes, then select "move to folder" in the bottom combo, and hit go. This should give you another page with a combo containing your custom folders. Then click "move items".

Hope this helps.
