I go to a folder, say, Sent. Re-order header columns, add those I want, remove those I don't want. Click on different folder. As soon as I go back to the folder Sent, the columns are reset to default (both the order and what columns are displayed). I tried going through Apply To Folder menu -- still no effect. Tried to delete MSF file for folder Sent -- does not help. Every time I go to a folder, its columns are set to default display.
