Yep - but should't mapped drives added/deleted directories... be auto refreshed into the "Folder" view?
I don't believe it's meant to, although that would be a nice feature for a future version!
It's easy to add a hotkey to File/Refresh; too bad it always shifts the focus to the "Folders" pane. It might also be nice to have a TCC command to update that pane. We could use aliases to bolt it onto NET USE, SUBST, EJECTMEDIA, whatever....
