WebDoubler Update Corrects Sherlock Proxy Bug -- A known bug in Apple's Sherlock can result in error messages instead of search results when using Sherlock through a proxy server. The problem stems from Sherlock generating incorrect HTTP headers. However, people using Maxum's WebDoubler caching proxy server on the Mac can now download a free 157K WebDoubler plug-in that corrects these malformed Sherlock queries before passing them on. If you're on a network, you can download the time-limited demo version of WebDoubler, install the free plug-in, and route all Sherlock queries through WebDoubler both to avoid the problem for a while and to test WebDoubler.
