In version 9.0.0.7, I can no longer double-click on a dotted vertical line in the tree pane in order to collapse the directory grouped by the line. Is this a necessary consequence of the new feature where one can double-click an empty area in the tree pane and go to the parent folder (or run a User Command) or did it just break when the new feature was added? Is there an option I can set to restore the original behaviour?
This must have inadvertently changed in some of the recent work on the tree to make it more Explorer-compatible. This was certainly never the intended behavior anyway - a double-click on the name is meant to collapse/expand the branch, but clicking on the lines is not meant to do anything.
