I have a header/wrapper layout where both div#header and div#wrapper are absolutely positioned, and on load i calculate the top property of the header and height property of the wrapper to ensure that the content is scrollable in the wrapper (overflow is set to auto). For some reason on IE7+, once the content has loaded and the calculation is done to set the top/height of the divs, it "hides" the wrapper and only the header is displayed... that is until you resize the window, even slightly- resulting in the correct display of the header/wrapper.
Could this be related to the overflow properties? There are no JS errors in the console and it seems like the page on IE doesn't render the overflow correctly.
Any thoughts or suggestions would be appreciated...
