The page here (http://skergeth.net/slidingfooter/) contains a footer that slides up when you click on contact us. It then shows a contact form.
However in IE8 it slides up and the div containing the form stays white until it is hovered by the mouse. I also tried the approach that the footer-div has overflow:hidden but since there are other elements inside the footer that should overflow (a menu that extends to the top), this is not an option.
I don't think it is a javascript but because I tried to delay the transition and made sure, the setVisible is called before it but with the same result.
I hope I made myself clear.
Thanks for all your answers!
