MSIE has an annoying misfeature: a web page can somehow say "raise me to the front". I hate this; I start a page loading from a slow server, then raise some other window on top to do something else while the page loads. Suddenly bang the slow server page is back on top, stealing focus, sometimes several times.
What's in the HTML that causes this in MSIE? This isn't popups; that's a different problem with plenty of solutions.
