Thank you ohillary.
Can you detail the operation you are doing when the folder is not showing, and you need a right click to reveal ? (I guess you're talking in the search pane).
Also, are you in "simple" or "advanced" click mode ? (see Options)
Any click should show the corresponding bookmark, so if not, there is a bug which I need to correct :-)
