I've added text to the book and now it chokes at compiling. The reported problem is with this text: "variables) to describe their objectives and actions needed to achieve them." and the error window is shown in the attached screenshot.
There were no problems compiling the document before and a search of the terms shown in the error window (bypass, california, 2004, 2005) do not show up in a search of the text. I've no idea where to look for the source of this error and would appreciate a pointer or two. Rich
