OWA user can not high lite

[AO3]

When the user clicks on a message, the blue highlight across the screen does not appear. I have reset IE7. I have accessed two OWA servers from the users cpu. Both OWA do not high lite. If I use a different CPU there are no problems.

Try running iexplore -extoff to load ie with no add-ons and see if it works like that
