EBay UK search hanging

Knowing that there's a few EBay users on the list who also know how to fix modern software... :-) On the rare occasions that I do actually bother to search EBay for anything classic computer related I quite often find that hitting the search submit button just hangs, with the browser (Opera under Linux in my case) sitting there saying "Waiting for DNS confirmation of cookie domain(s)". If I open another browser window at this point and then try and go to any other site it'll just sit there with the same message. If I close the browser and come back later it's fine. Very frustrating. Anyone else see this or know what causes it? I've *only* seen it happen trying to do an Ebay search, never with any other website - but it's been this way for months. Whilst it's hung like this in the browser I can do DNS lookups from the shell fine, so it's not a DNS problem or a local configuration problem. I assume Opera happens to use shared DNS lookup code and for some reason something to do with EBay's search *sometimes* makes it hang. Presumably others might be able to shed some light on this, or at least confim / deny that they've seen similar problems with EBay UK from different platforms and browsers... cheers Jules
