[MlMt] permanently killing Organize by Thread

[Shoshanna Green]

Every now and then, Mailmate spontaneously turns on View — Organize by 
Thread. I hate threaded view and never want it. Is there a way to 
prevent this from ever happening? I mean, I'm sure this is a minor bug, 
and it's probably relevant that unwanted columns, such as Read, also 
sometimes spontaneously reappear in my mailbox view. But Organize by 
Thread sometimes turns on without any unwanted columns appearing, and 
it's more annoying than the unwanted columns because sometimes I don't 
realize for a few minutes what happened and start worrying about where 
all the missing messages are, because I can't see them in the message 
list any more. So I thought I'd mention it.

(I know that I'm not accidentally turning on Organize by Thread myself; 
it happens — unpredictably and not often — when I switch to viewing 
a new mailbox, which I do with one- or two-character shortcuts defined 
in a keybindings plist. There's no way that I'm accidentally typing 
shift-option-t when I mean to type i or d or gr!)
