Hi, folks: Since installing IE7, I noticed that iexplorer.exe 's CPU usage has been fluctuated on my 2 laptops. I did not know why and have no remedy UNTIL.. My friend oversea emailed me that Microsoft knew this issue and has since included the patch in auto d/l for VISTA users ONLY..... WinXP loyalists have to d/l the patch manually from microsoft's site if you have known it. I have just done that, and immediately feel the damned--late coming differences. FYI, the patch IS KB928089. It is evidently not on my Window updates list until now. Take care.
