The top links area looks ok when you are logged in. However, it looks all messed up when not logged in.
Have a look at the image below. Notice the blue box around the sign in area. This background colour takes the value of whatever is set in navbar_tabs_background. This seems very silly to me i.e. having the background colour of one class control the background of a completely unrelated one. I'm not sure why this is background box even there in the first place to be honest.
This brings up a problem. I want to remove the blue background but the only way to do it is to set the navbar to white, which I don't want. So, the only solution I have is to set the toplinks to white.
However, this brings up problem number 2. Notice the remember me text underneath the top links? No, well that's because the remember me text takes on the colour value of the top links, even though it is text and not a link.
Seeing that we are now in patch level 1, I really think this is something that needs to be addressed.
