I was nearly ready to jump from test mode on a PHP site I am constructing (in other words everything was looking perfect in IE, Firefox and Chrome) when suddenly the wrapper on all pages has skewed downward and the layer that holds the logo is disappearing and reappearing on refresh when using IE (you can see how it should look by browsing both FF and Chrome). I am not aware of changing anything in my CSS so am completely puzzled. If anyone could take a look and guide me toward a fix it would be much appreciated!
