1) I log in to a server.
2) I am presented with a list of files in /root, not including the ".." directory.
3) I refresh (F5) or cause a refresh indirectly by copying a file.
4) The ".." directory appears in the file listing.
Personally, I would like it if the ".." directory were never displayed, like in earlier versions of WinSCP (1.x, 2.x), but maybe an option in "preferences" would be better.
The reason this matters to me is that my default directory contains a bunch of soft links to places where I like to copy files. The appearence of ".." messes up the alignment of the directories in the UI.
