[MlMt] Changes in message list header not kept.

[Eelco Chaudron]

Hi,

I'm running Version 3.0 (7031), and when I go to a specific mail folder and change its list heading layout (add/remove fields, change width), if I go to a different folder and back it is restored to the previous values.
Don't know when it was introduced, as I change monitors and have a small one now, so I need to change the layout a bit.

Cheers,

Eelco
