Disappearing Menu Bug in IE7
Here we have an interesting effect that drove me nuts for about 6 hours one day. This isn't exactly the same but if you just click this link (which is simply a link back to this very page) enough times... the menu will disappear. Click it again and it might come back (it usually does). When I had the whole site working like this using the back button instantly stripped the menu from the page and wouldn't come back until you hit refresh.
Try it if you're using IE7.
When I changed the link div (navigation) to position: fixed; this bug appeared in IE7. I found a style sheet that didn't do it and started looking through it. Finally after hours and hours I discovered that having; clear: both; in the footer div was causing the problem and changing it to; float: right; made the bug go away.
