Please confirm whether you have checked the option "Disable all text styling options (never send styled mail)". This option changes between a mode where line length is measured by the number of characters and the more word processor-like measurement by millimetres (or inches).
I use plain text most of the time but I actually use the second mode, so I just want to clarify what your settings are, even though you say you use plain text.
EDIT: I forgot to say also that I wonder whether you are failing to notice the line extending off to the side of the window. I can make my lines continue to the right of the editing area before wrapping. I don't get a horizontal scroll bar so its not obvious - at least when your line consists of "wwwwwwwwwwwwww..." rather than normal words.
