I have found that when using pagetree (or the left panel navigation tree - perhaps one and the same), if I expand the tree to navigate down to a page I want to see, click on the page, and then return, the tree is collapsed. This can be very annoying when you are trying to view more than one page at a lower level. Is there a setting which controls this behavior? Unfortunately, Windows Explorer has trained me to expect the tree to remain expanded. It feels like I spend a lot of time expanding the tree, and then re-expanding the tree, and then... You probably get the idea.
