> I have a page with a 500 row table.  Each row has a "delete" link that brings up a modal panel.  The modal panel takes 4-5 seconds (with CPU spiked) to appear under MSIE 6 or 7.  The time it takes to show up is proportional to how many rows in the table.  If I have a small number, the modal panel shows quickly.  The problem appears to be due to slowness in the modalPanel.js preventFocus() function, which is called from the show() function.  
> My test page wasn't very complicated, with a bean providing a list of 500 objects.
