Yep, changing font "fixed" the problem. It's a puzzle why someone thought would think that this would be a good way for the rendering engine to work. I can think of a few of reasons for it NOT to behave this way, and none for why it's a good idea. I'll have to dig in and see if there's a way to turn it off. I'll look at the details of the font as well; I'm not at all sure what exactly is telling TB "if you see two consecutive "less-than" signs, then render them as a single "much less than" character. No other program seems to be doing it, so it seems to be a TB decision somewhere; but since it seems to be font-dependent, TB must (presumably) be looking at some characteristic of the font before deciding to make the substitution. Very strange. Thanks for the suggestion that it might be dependent on the font. Doc -- Web: http://enginehousebooks.com/drevans
