The difference from what I did and what you did (and this is a guess), is that I created my test cells with the less than as an Input cell and then changed the style to Text. So I created another test case with the cell being created as a Text cell initially, and sure enough it shows the problem. So two workarounds are available: 1. Create your cells as Input and convert them to Text with the Format/ Style/Text command 2. Use another type of less than, e.g. \LessSlantEqual which does not seem to have the same problem. Wolfram, you have a bug - IMHO. Because the problem does not occur in both types of Cells (Input and Text), I sure would guess the problem is Mathematica's and not a PDF/Adobe problem. -Bob
