Looks like it was a corrupted Paypal cookie lurking about on my test machine. Clearing all Paypal cookies cured the problem. Hours can be spent looking for needles like this in a very complex haystack and it turns out to be the simplest solution that's not even related directly to the programming. Thanks, Andrew for the prompting! However if this happened on a punter's computer the same would happen - so is there a way of coding the removal of third party cookies to avoid this problem?
