When uploading to SmugMug, when I create a new folder or gallery, the import dialogue does not refresh properly -- instead of showing the new gallery it duplicates a previous one in the list. It also does not show a new folder or a new gallery when it is the only thing in the list upon creation. You need to click away on another folder, then click on the original enclosing folder to see th new folder or the gallery.
Update: when you create a new gallery, it duplicates the top entry in the column where the galleries are listed. When you click on the topmost one, it is refreshed to the new one. So it's a question of simple refresh.
