Try making a copy of the document and opening the copy.
Paul, I'm taking a different approach. My last book, published by Springer, used the svmono.cls/svmono.layout so I figured out how to use it as the current book's class. Still no Check TeX in the Tools menu. However, ... Opening a new document which is the svmono template, it does have Check TeX in the Tools menu. So, tomorrow I'll cut-and-paste from the document I started to the template, then save it under the desired name and move on from here. That should fix all issues. My thanks to you and Scott, Rich
