overflow:scroll bug in IE
If, for some reason, you’re trying to put a relatively positioned element inside a container element that has overflow:scroll, the child element will display in IE as though it had position:fixed. The way to fix this is by giving a position:relative to the container element as well. I think this is important from two standpoints: the bug has been preserved in IE7, and you can use it to hack your way to position:fixed cross-browser bliss (or so I hear).
Just thought I’d share. Via a forum reply that belongs to Jack Sleight. Thanks Jack!
