Paul,
Has anyone encountered such a problem when I
click an underlined word in the Microsoft Office Help : A
pop-up window said "An error has occurred in the script
on this page. Error: Object doesn't support this
property or method."
Here are some things to try:
1) Upgrade the components used to view HTML Help files by applying
Microsoft Critical Update 811630.

2) See the following article in the Microsoft Knowledge Base, which
may explain the problem.

If this is the case, you may be able to restore the popup
functionality by replacing Ouactrl.ocx with an earlier version (on the
installation CD). However, this may leave you open to the sort of
attack that the security update was meant to stop.
3) Delete the file hh.dat, which you should find in a subdirectory of
\Documents and Settings.
This is a database file that saves such session information as the
window position and favourites for the HTML Help viewer. If the file
has been corrupted then .chm files may behave erratically. Windows
will automatically re-create the file when you next open any .chm
file.
4) Empty your Temporary Internet Files (TIF) directory. A full TIF
directory can cause HTML Help files to misbehave.
5) Use MJ's Help Diagnostics to check that the HTML Help viewer
components are properly installed and registered on your machine.
