When you really start getting into CSS, you really start to hate
IE6.... Personally, one of the most annoying things I have found is if
you use a background image on a link, when you hover over the link in
IE6 the background image seems to disappear then re-appear.. A
flickering effect.
A quick and quite brutal way to get round this
is to add the following to you code, either add it to the page as shown
below or just just it in your external JavaScript file
[CODE]<script type="text/javascript">
//<![CDATA[
try {
document.execCommand('BackgroundImageCache', false, true);
} catch(e) {}
//]]>
</script>[/CODE]
