Suzanne,
       many thanks for your response which although
helpful, does not quite solve the problem. Should point
out here before I go any further, that in this case we are
using Windows 98 (not SE) and Word 97. The issue we have
with Word is when you click on Insert->Comment, the users
intials appear in the main body of the word document
highlighted in yellow. Your tooltip remedy allows the
colour of the box into which you subsequently enter the
comments to be changed, but the initial yellow 'inverse
video' highlighting remains. I know this sound bizarre,
but we have a customer who finds the yellow colour a bit
of a problem. Is there any way we can affect, what appears
to be, inbuilt highlighting?

Many thanks

Ian T.
