The latest build contains a minor cosmetic flaw which has been present in recent beta versions:
When first opened, the Navigator pane will list folders with no triangle to indicate the presence of sub folders. Double-clicking will not open these folders. However, collapsing the Parent Folder and then reopening it restores normal indication and operation.
