Kmail in 4.2.4 -- another old bugaboo has come back (does so every so often): The columns in the various view-panes do not scale correctly to pane width. Folder panes, for example, will not show unread and total mails without a horizontal scrollbar--I had gotten around that before, somehow. The folder- contents pane will truncate rather than rescale but can be set up properly by dragging.
