Q: My ASP.NET site’s menus show as blank/white when my page is rendered in IE8 standards mode. The menus only work if I turn on compatibility view. What’s up with that?
A: This is actually a standards-compliance bug in the ASP.NET framework. A fix for ASP.NET is available; see http://support.microsoft.com/kb/962351
