My client has noticed an issue with the plugin on IE9 which I have noticed on my own version of both IE9 & IE8 here.
When creating a new post and adding a recipe using the fork and spoon icon above the WYSIWYG editor it all works fine. Until you hit publish, at which point the recipe graphic (and recipe information) vanishes without trace from the editor.
Is this a common bug? Anyone else found a fix?
