I just found out that form elements on top of images in img tags get no focus in IE8.

so if you build a form in an overlay and use the apple effect the form ist not usable.

this can be fixed if you hide the the background image in the img tag after the overlay is loaded an you reactivate the css background. and befor you close you does this rewise.

perhaps it could be useful to implement this as standard in the apple effect!?

thanks.
