it's the general shortcoming of the site designers. they COPIED MICROSOFT MSDN website! that's enought to know it's no good :)

and that's even bad while viewing in the desktop. if you increase the font, if increase the header, to the point the header uses most of the screen space!!! how wants to see the header?!?

just don't use the header/sidebar fixed like that. it just breaks the browser scroll functionality. in every browsers.
