Div overlay hue issue only in IE8

Please visit http://www.in2medical.com/ with IE8. There seems to be some sort of lighter hue over the dark blue bar (in which the logo resides) on top. This hue is not visible in IE9, chrome or firefox.. It looks like in IE8 the div in which I place the content and I position on top of the background is automatic开发者_JAVA百科ally changing the color of the div over which it lays. How is this happening?

Save /images/bg_logobar.png without the embedded colour profile.

I did it for you, but you need to learn how to fix it yourself or you'll have the same problem again.
