It is linked to the Tooltips provided by Joomla and occurs usually on large pages:

The simplest solution is to change:

/libraries/joomla/html/html/behavior.php
~line 108

$tooltipInit = ' window.addEvent(\'domready\', function(){ var JTooltips = new Tips
($$(\''.$selector.'\'), '.$options.'); });';

To:

$tooltipInit = ' window.addEvent(\'load\', function(){ var JTooltips = new Tips
($$(\''.$selector.'\'), '.$options.'); });'; 


Or you can turn the Tootips off.

Or you can do as Microsoft suggest and persuade your users to upgrade to IE8 or just use Firefox!
