Thanks Shawn. I see what you mean. Seems to me that it worked fine the first time I tried it with sticky notes yesterday. Practice, practice.
Edit:Give this a try. Move the mouse over the arrow and let the list open. Then right click on the little arrow. This will, of course bring up the open/pin menu. Move the mouse across/over this menu and then to a blank space on the list, if what you want is covered, or to the item you want to select and click. When I click on a blank spot on the list, open/pin menu disappears and the list remains. More work than it should be, but works and maybe they'll get that fixed by final release.
