Actually, in text editors, it can be a good idea. Easier to keep track of which line of code you're working on. It depends on whether the wraparound function is enabled or not. A 200 expression line can be cumbersome but wraparound occasionally makes me loose my place which is even more annoying.
I take it that some of you are simply seeing the "word" get cut off as though it were going under the edge of the post box. I'm seeing the text. Firefox gives me a bottom slider to read the whole thing. Internet Explorer just cuts it off at the screen.
