Thank you fruhulda, that's a good suggestion. Thanks also for the instructions on finding the Library that is so well hiiden in Lion!
I'll wait to pull the plist until I have completed a currrent document of 120 pages that has lots of critical formatting. I'm afraid of losing any important settings. Then I'll do as you suggest. I do appreciate your help.
For problems with the help viewer you need to delete the .plist file associated with the viewer not the .plist for the app you need help with.
Go to ~/Library/Preferences
Move the com.apple.helpviewer.plist file from the Preferences folder to the Trash.
Restart your Mac.
~ (Tilde) character represents the Home folder.
I'd back up a few steps here.
Skip the Help viewer, which is searchable using a pre-built table of contents/index.
Go to the Help menu and download the Pages '09 User Guide, which is a PDF document in which every word in the document may be used as a search term.
Same topics, pretty much the same information, easier to search,
