Running 0.4 beta. Tried the 'threading' function from the pop-up window. Selected threading and sort by subject, but only a few messages appeared threaded for some reason. Turned off threading and sorted by received date again. Column order is now different from before -- "sender" is after "subject" and "attachment" is at the end.
Values for "list_cols" have not changed in main.inc.php.
This entry suggests that "list_cols" is no longer used because columns can be re-ordered with 'drag and drop'. How is this used? I can drag a column and drop it somewhere else, but it does nothing. How do I restore the column order?
