Hi Peter,
It looks like you're almost there! One problem you may be having is your browser. Scott can tell you the exact release that doesn't work, but I can tell that at least IE9 works. If nothing else, you can change your config to use Firefox.
Try going to the window on the left of the screen you are showing and picking "Workspace".
If you don't see that or the "Common Folders" tab, you may have to pick the little icon that looks like multiple folders. See attached image and let us know if that helps.
