One oddity I just noticed in the beta 3... if you have no folders created in the root, then the left-hand navigation pane doesn't show the Control_Panel, Quickstart, or acl_users folder. Once you add a folder, then all three of those objects, as well as the new folder, appear in the left-hand pane. If you then delete the folder, and refresh the browser, everything in the left-hand pane disappears again (leaving only the root folder at the top).
Not a biggie, but a little odd.
What client are you using? I'm not able to reproduce this here :( I suspect some sort of client rendering problem or maybe a stall or truncation of the page somehow? If you view source on the nav pane do you see a complete well-formed html document missing those items or a truncated file? Note that some clients will show you the latest cached source when a page didn't load all of the way, so be sure to refresh the pane manually as well.
