Whay have my Excel hyperlinks stopped working?
 

,I have routinely used hyperlinks in Excel to create an address book linked
to pictures. For several years, they all worked with no problem. Suddenly
none of my hyperlinks work. When I hover over the link, I get the disply
about the path - and it is correct - when I click on the cell, the cell box
(current cell) disappears and the window is no longer active, but the new
window (containing the pic) does not appear.

I have done no major changes to my system (that I am aware of - you know
that some programs "update" without permission).

I have run Norton virus scans and found nothing.

Help!
