I have the option "Expand to current folder" selected on, but some of the folders in my favorites list do not show the directory in the tree view, while others do.
In particular, my documents folder does not expand the tree view, but shortcuts to most folders within it do expand (one such shortcut does not).
The only observable difference is that the ones which don't expand are displayed in the path field at the top of the window as "username > My Documents > path > to > my > folder" while those that do work display as "Computer > System(C:) > path > to > my > folder". In all cases clicking in the path field changes to a normal folder path from the drive root.
Why is this?
