Holiday:

I'm not certain this is the full answer to your question. The sample cover-sheets that come with Adagio modules often break the line in the wrong spot because they have embedded end-of-line characters. If you are editing the body of a cover-sheet, use the mouse to make the window wider. If any lines break too early, delete the invisible end-of-line character at the end of those lines with the [Delete] key.

But I have a feeling there is more behind your question than that. For instance, if a URL gets chopped, what tells you it's Adagio and not the mobile device's email viewer?
