Having installed IE9, it seems that the Avisio theme may have a problem or two rendering correctly in IE9 standard (non compatibility) view.
First problem is that the Homepage 'Slider Entries' UI/images don't show up - it shows a loader image permanently, and,
Second problem is that the heading fonts (as rendered using Google font API) don't show, so no headings and therefore no links.
Is there a planned release to help with this?
Edit (Add): Forgot to mention that the only way I can get Avision site to work at all adequately at the moment in IE9 is to force it into IE7 compatibility mode (X-UA-Compatible / IE=EmulateIE7); - this at least allows the google fonts API to function so Headings/Heading links show up/work, but the slider will only appear after several page rerfeshes!
