On the home page, if you try to insert some work in the text entry widget for search keyword, at the top of the page near the "Search" button, characters entered don't get displayed.
Page servers up a bunch of different style sheets depending on the browser and OS. For "Netscape" on Unix the style sheet sets the text color for that <input> to white. So of course you don't see anything (it's white on white). This is a bug in the page. Evangelism.
