navigation bar and image overlapping, cant figure out how to fix

[bkjfdghiuds]

ive been changing around the height values for everything but nothing seems to push the navigation bar down next to the comments. when i have a slideshow, the slideshow ends up blocking the navigation bar.

here is an image of the problem.

here is the css on pastebin.

can anyone take a look at it? thank you!!

the only thing i figured out was

.single-projects #content {
    width: 980px;
}

//changes right/left of navigation bar

well am happy to tell you that the picture is not clear...at all

so you are saying that another window is overlayed on top of your main page, blocking the navigation bar?
