BuddyPress Social Theme Bugs

Hi I've found two bugs while working with BuddyPress Social Theme. Using windows 7;

The first bug is found while using IE. The Header(black) should be all the way at the top of the page, instead there is a white space that should not be there, it work fine in firefox.

The second bug is seen in both browsers. When you browse to a new page using the navigation, and you choose the About page the background hover color of the home page stays on. The color of the home tab should be grey like the other two in the example because you are on the About page.
