Acerca deste extra
Then No Message Pane Sorting By Mouse is the addon you've been waiting for. It disables mouse buttons clicks on the message pane headers and your message list stays sorted all the time. But just in case you do need to resort your messages: You can still do it by ctrl-clicking or command-clicking on the header.
I'd like to thank you for using this little addon. If you have questions, please, let me know.
I do realize that the addon's name is a bit clumsy. I'd like to have a better name for it, so if you have a suggestion I'd love to hear it.
