Are you sure? Normally, none of the *-headings are supposed to appear in the TOC (that's what the star insicates, amongst others). If you want unnumbered sections in the TOC, you have to do something else. Here are some possibilities: (1) write \addcontentsline{toc}{chapter}{<the actual chapter text>} in TeX-mode just below the Chapter*. If it's a Sction*. replace "chapter" by "section". (2) use KOMA-book as a class and use "Addchap" and "Addsec" instead of Chapter* and Section* (3) if you have only unnumbered, no numbered headings, just use Chapter and Section and set "Numbering" to "no" in Document->Settings->Numbering & TOC Jürgen
