Anyone who have fixed this before?

Pushbutton site-info skewed 3px down in IE7, fine in FF3x

In Firefox 3.x it works, but IE gives me an extra roughly 3px "border-top" right above the "#site-info".
I am trying to use a background image there, which needs to be aligned with the header-a and header-b images to the left and right of it (all part of one wide background image, split into 3 due to the nature of this theme.
However, the middle part is skewed (pushed) roughly 3 px down, with the same border color on top as the menu links border color, it seems. Trying to switch to a jpg instead of a png does not help, and the PNG-behave module does not affect this either.
Anyone have a clue how to work around this annoyance?
Seems to be related to a bug in IE?
