Site delays in screen-scraper but not browser

http://www.browncountyclerkofcourts.org/Search/srchmain.shtml

If you search on that site for a name that doesn't have any results, like "JONES, AMETHYST" it comes back almost instantly with a "no records" page/message.

In screen-scraper, the same call takes a LONG (30 seconds+) time to come back, and when it does sometimes the server has responded with a timeout from their database.

I've tried many combinations and would normally write it off as "their server has issues" but cannot for the life of me reproduce the long delay in a browser. Have you ever seen anything like this? Any ideas? I can send you the scrape I'm using -- but it's just the a recorded proxy added to a scraping session and replacing the name searched, nothing funky.

If I go to the site in Opera

If I go to the site in Opera 12, I can search lots of names that get no results (example "Bellows, Jason"), and I get a quick response from the site and the scrape. If I search for "Jones, Amethyst" in either, however, I get timeouts.

Honestly, it looks like the site is choking on the one name for reasons unknown.
