In a stylesheeted flash

Stylesheets are great, of course. They remove much of the annoyance in making HTML look pretty. But why oh why must the entirely CSS'ed page designs render a non-styled version of the page half a second before showing the real deal? I understand CSS is supposed to be optional and displaying a HTML page before all the elements have loaded (such as the stylesheet) is great and all, but still. There must be a better way that includes not flashing a non-styled page. Or at least there ought to be one. Update: Opera 6.0 has no such problem
