Hi,
For some reason the navigation toolbar "greyed out" when my wife was using Ebay.
T he back and forward buttons and the refresh and cancel buttons are effected. Any ideas please?

What browser? If it recently updated the browser, it might have
Changed something.

I have just set up a secondhand replacement PC and all has been working fine until eBay has been in use. The PC had only IE in use so I downloaded the latest Firefox version to use as this is far superior in my opinion.
All other aspects seem to work fine.
