Background flicker problem in Internet Explorer

I have several pages with a background image applied to the body of each one of them (same background image for all pages).

When I go from one page to another开发者_开发百科 it looks like IE7 renders the image again, which looks like flickering.

In Firefox 3.6.3 it does not flicker.

How this flickering can be solved for IE ?

IE's caching of CSS background images basically sucks. There is a microsoft filter for your CSS that should fix it (proprietary, of course, so you may want to disguise it in a conditional comment):

html { filter: expression(document.execCommand("BackgroundImageCache", false, true)); }
