BuildID: 2001110903, Win98 Customizing the column header displays in the Mail windows causes problems, including alignment and the message list dissapearing alltogether. Stept to reporoduce: - Open MailNews - Click the column header toggle button and uncheck Thread (Notice how the email list did not update & shift its contents to align with the proper headers). - Switch to a new folder. The email list has now dissapeared. The only way to get the email list back is to turn on the Thread column and switch folders once again. I don't like having the Thread column on in Mail as it wastes space, so I usually turn it off. I am now forced to have it on in order to read my emails. I'm attaching an image which shows the various steps & results.
