When trying to sign-in to eBay on my laptop (Vista) it crashes out with a white screen saying "http://1.1
Service Unavailable", but has previously worked fine.
If I sign-in using my desktop computer (XP Pro) there is no problem.
On the laptop, I do initially get through to the ebay sign-on screen (https://signin.ebay.co.uk/ws
...), but the URL changes to http://cgi1.ebay.co.uk/aw-cgi/eBayISAPI.dll?MigrateVisitor&PageType=1883
just before the crash.
The problem first occurred when I was using the laptop in France earlier this week, but it has always worked in France OK before.
