This is really a disaster. The page zoom does not happen in appended Child Nodes by the dom. This is really a disaster.

When zooming from 180% to 140% it only fires when it's 170% and 140%. Between 120% and 130% the event never fails to fire. Some more notes:

Turn quirksmode off, and it skips the occasional event. I noticed also that in quirksmode, IE7 definitely fires the onresize event each time the page is zoomed.

This catches percentages like 75%, and your code wasn't catching 110% properly. Also, there's no point setting a timeout if the function only gets fired on a window resize (in IE this doesn't happen every time!!!!). Use an interval instead (or use both). I know an interval is not graceful, but... Also, if you use an interval you can put it within the init function for when the document gets loaded. Some comments:

I was always wondering what IE6 programm you use to test IE6? I have a software called Multiple IE which can allow both IE6, IE7 installed. But I found IE6 under Multiple IE doesnt render HTML pages the way stand alone IE6 does. May I know what you guys at Yahoo! or you presonally use to do Multiple IE testing? Thanks in advance!
