I've checked all of the forums and the rest of the 'net for this problem! Hopefully somebody can help!
My WebHelp search function works prefectly well in Firefox 2.5 and later, as well as in Opera, Chrome, and Safari. However, it will never return a search result in IE7, on any of the computers I've tested it on (up to 8 different machines now... and I've cleared all the caches and reset IE to the default settings on each of them). It always comes back "No Topics Found".
