Editing Problems, Solutions and Workarounds

When I click the Update button the changes I made do not appear in the document

This problem has been encountered by users working at home. Changes were being made but the browser turned out to be caching the original version of the document. To correct the problem, Edit the Browser Preferences. In Mozilla use the Edit / Preferences / Advanced / Cache menus and check the Every time I view the page radio button. Other browsers have similar facilities but they may be elsewhere (try Tools?).
