MS Office Help Menus Problem

[Class 1]

I have MS Office 2000 running on W2K.

I've noticed that the icons in the help menus have disappeared.
This applies across all MS Office application (Excel, Word, PPt,
Project, Access etc).

For example, there should be 2 icons in this page from the MS Access
help menu, as defined in the code:

<TABLE ALIGN=right WIDTH=0 BORDER=0><TR><TD>
<OBJECT ID="hhobj_4" TYPE="application/x-oleobject"
CLASSID="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<PARAM NAME="Command" VALUE="ALink">
<PARAM NAME="Item1" VALUE="">
<PARAM NAME="Item2" VALUE="achowSettingPropsUsingCode">
</OBJECT>
<OBJECT ID="hhobj_5" TYPE="application/x-oleobject"
CLASSID="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
<PARAM NAME="Command" VALUE="ALink">
<PARAM NAME="Item1" VALUE="">
<PARAM NAME="Item2" VALUE="mdproFilter">
</OBJECT>
</TD></TR></TABLE>

However, they are not shown any more i.e. the link is broken.
Any advice on how to resolve this problem would be appreciated.
