## TeX fields

I am using SWP 5.5 (build 2960) in Windows 7. I wrote a book several years ago and occasionally edited it for student use.
Recently, I open the chapter files to find that tagged items (exercises, theorems, etc) now appear in grey boxes as TeX fields. How can view these fields with the screen editor so that I can edit them that way?

### SW knows about the

SW knows about the theorem-like environments from \newtheorem statements in the document preamble.

My guess, you are using subdocuments and the master document where the preamble information comes from is not being found.  If that's the case, restore or recreate the master document with appropriate \newtheorem statements.

For sample \newtheorem statements, start a new document using a similar shell, for example one of the article shells in the Standard LaTeX shell directory.
