Version: 4.8 (using KDE 4.8.0) OS: Linux I sometimes miss a correct spot when clicking with mouse, so I accidentally change sorting of the message list. As bug 227516 is still existent, it's especially annoying as for me it isn't just enough to click on another column to re-sort messages the way they were before - for an instance I have to first re-make visible the Sender-column, adjust the columns' sizes to the previous state and then go: Right click -> Sorting -> By Date/Time of Most Recent in Subtree. Reproducible: Always Steps to Reproduce: Click on column headers Actual Results: Messages get re-sorted by the column clicked on Expected Results: It would be nice if it was possible to lock the columns (eg. like it's possible to lock toolbars), so that it wouldn't be possible to re-sort messages, change the order of columns, resize columns etc.
