We are having a problem with Word's Outline Numbering feature linked to Word Styles. It doesn't always happen, but it has happened often enough that we need to try to find a reason for it. When using Outline Numbering, when we try to modify the Number format box, Word freezes, displays the error "The document is too large for Word to handle" and End Task is the only option. For instance, if level 3 has (a) and we want to modify it to be a., we go in and try to delete the () around the a, and Word freezes. Has anyone else experienced this? The unfortunate thing is that it does not always happen, so we haven't yet pinpointed a cause/solution.
