I have bought an article on eBay and wish to pay via Paypal. When I link to the Paypal site I can input my login and password OK but when I click to 'Confirm your payment' the process starts and then freezes and the payment does not complete. The 'Loading' logo on the page stops and the 'Reload' arrow in the location bar changes to the 'Stop' X. If I click to Stop it presents a white page and does nothing. The content of the Location bar is copied below.
