I have XP, Microsoft Home/Student 2007. I'm working on a long Word document (about 160 pages) that contains review comments: only about 10, but about 10 reviewers are named in the reviewers tab. The file crashes consistently when I navigate to a tracked change, show/hide reviews, make an edit, save the document. I've defragged the hard disk. I've re-created the normal.dotm template. I've looked at the paging size. I've tried running diagnostics and repairing the file. I'm not having the problem with shorter documents. The document was created in the version I have at work, Word 2007 enterprise.

Any advice?
