In fact, this effect occurs in almost every case where text is added to or removed from a line of `free' text, also in the `fill-in-the-blanks' and `backwards' example. Personally, I take this to be an ideosyncrasy of acroread, which apparently tries to optimize the appearance of a line, creating slight differences in character positions and stroke thicknesses depending on which characters are displayed. I couldn't reproduce the movement with ghostview (neither for ps nor pdf) or xdvi, but then again it's hard to verify such things with a viewer clearing the screen between frames... Anyone care to make screenshots and calculate the `true' difference with an image manipulation tool? regards Stephan -- Stephan Lehmke [EMAIL PROTECTED] Fachbereich Informatik, LS I Tel. +49 231 755 6434 Universitaet Dortmund FAX 6555 D-44221 Dortmund, Germany
