When I select a folder with the columns and column widths set the way I want, then do "Apply current view to > Folder and its children > Local > Local" Thunderbird applies the view to some, but not all, folders. Even if I target a problem folder and explicitly attempt to apply the desired current view to it, it doesn't work. If I create a new blank folder as a sub-folder of a folder that *does* accept current views, I can't apply the current view to the sub-folder. It retains what appears to be a default view.

I can't see any difference between folders that accept "current view" and those that do not. Any suggestions? Or is there a way to set the default view (i.e., columns and column widths, not just sort order) for new folders?
