Hi,
Is there have Space or Enter symbols in the Page 3 ? If there has, please select all space and Enter symbols and delete test if it works.
This is cannot accomplish that only lock 2 pages, and let user edit others page.
Maybe Restrict Permission would help you:
Restrict Permission enables you to limit the functionality of a document while still allowing others to view it, and, if they have the necessary permissions, work with it. For example, you might want to set options that block the print or copy commands so that
others cannot print copies of your document or copy and paste sections into other files.
NOTE The Restrict Permission feature is available only in 2007 Microsoft Office Ultimate, available through retail outlets, or 2007 Microsoft Office Professional Plus and 2007 Microsoft Office Enterprise, both available through volume licensing.
