Well it's certainly interesting stuff, if not a little complicated, I'm glad you included example 4, which shows a practical application. the other examples are throwing an error in IE5.5 at the moment. I don't quite understand why you limit the screen size to 800*600, or is that something else? Is this controlling the visibility of browser scrollbars in NS4/IE ? what are the main differences (apart from the implementation) between this and Henrik's layerpos? http://www.resass.f2s.com/dynapi/Henrik_Vaglin_Examples/ccreation.ext.layerp os.htm (url wraps) Keep up the hard work, have you reached any conclusions on the timing issues yet?
