Thunderbird Layout Settings Troubleshooting

Hi,

I'm starting to use portable thunderbird and I have this question. The columns order can't be saved after I reorder them. They start always in natural order. I add new columns like size and account and when I restart TBP they are not there. The same is with message pane. I click F8 to hide it and when I restart TBP, there it is the message pane.

Why can´t TBP save the layout I made?

Thanks!

Sean
