I thought I'd download IE 9 beta for a laugh today so I could see how it rendered the Avisio theme. There were a few rendering issues (that i'm sure you already know about) including: missing footer headlines, corrupted big button ('our latest work' on your demo) on home page, plus 'flexibly frontpage' title (part of 'Why Avisio') wrongly positioned.
OK, I can understand that it's IE 9 beta so therefore these issues may be sorted in the final release but, when I try developer tools and insist on rendering like IE 7 I still get issues with both IE 8 and IE 9 browsers. It's all good in IE 8 but it needs to be good in at least IE 7 and hopefully IE 9. HELP! Is there a work-round?
