GNOME Bugzilla – Bug 411768
Dragging a column header up or down causes it to disappear
Last modified: 2009-10-15 18:20:10 UTC
1. In the message list, drag a column header above or below the list of column headers, and drop it. What should happen: Nothing. Like a horizontal scrollbar thumb, the column header should slide only horizontally, not vertically. What actually happens: The column header slides back to its original place, the standard method of indicating that a drag-and-drop has not done anything. But then the entire column disappears! A more appropriate way of hiding/showing columns would be with a "Columns" submenu of the "View" menu. ("View" > "Current View" > "Messages" works, but that is not obvious, and it undoes any other customizations that you actually wanted.) Problem occurs with: Evolution 2.8.1, Ubuntu 6.10 Does not occur with: Thunderbird 1.5.0.9; Outlook Express 6; Apple Mail 1.3.11

Created attachment 130136 [details] [review] proposed evo patch for evolution; There is a context menu over a table header, thus this patch just doesn't remove column when dropped out of the header.
Description of Milan's patch sounds like it would do exactly what I suggested downstream. See https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/344373
Created commit a0bf55c in evo master (2.29.1+)
