W3 Total Cache and IE9 not rendering

Hi,

If i empty all caches from within wordpress admin or delete a created page cache item from the server manually then as the new pages get added back to the cache they do not render correctly in IE9. Ive narrowed this problem down to something very odd. If the page cache item is created by an IE9 browser (e.g. an ie9 browser is the first browser to visit that page after the cache was cleared) it creates the page in the cache and all renders well, but if the page in the cache was created by another browser, for example chrome it looks good in chrome but IE9 layout doesn’t render correctly.

Anyone have any ideas?

Thanks in advance
