Great plugin but for some reason the icon image does not show in IE8. The square box that does show in its place follows the same style as buttons in the theme I'm using. It's fine in other browsers I've tried. Could be a conflict with sites css and the css embedded in the script - don't know.
I'm keen to use this as it's the best looking and least obtrusive 'solution' I've seen to this asinine, ill thought out EU edict.
