Using soft wrap, the text is wrapping every line at a character count significantly below the wrap margin value (not because of word breaks). The text is wrapping where the wrap guide is shown, and when I hover the mouse over the wrap guide the wrap margin value is correctly displayed, but when I count the characters up to the wrap guide the number is much less than the wrap margin value (e.g., soft wrap occurs after character 45, even though wrap margin is set at 75). Problem appears to be independent of font selection.
