I've circled the problem within a red circle.

See image attached.

Thanks upload3

Not sure what you mean by smeared, but have you tried using different browsers?

it looks smudged a little

Is it possible that you are having a padding issue? I'm not sure but maybe if you posted your css code (whatever you wish to call it) you might get a quicker resolution to your problem.

here's my css

#links ul{
    margin:0px;
    padding:0px;

}

#links li{
    display:inline;
    margin:0px;
    padding:0px;
    list-style:none;
    float:left;
    position:relative;
}

#links li a{
    display:block;
    width:250px;
    height:40px;
    text-decoration:none;
    text-align:center;
    font-family:Calibri;
    font-size:18px;
    color:#FFF;
    background-color:#373737;
}


#links li a:hover{
    color:#FFF;
    background-color:#5F5F5F;
}



#links ul ul{
    position:absolute;
    visibility:hidden;
    top:40px;
    height:200px;
    width:250px;
    background-color:#373737;
}

#links ul li:hover ul{
    visibility:visible;
}

I see some smudging in the picture, but I assume that's the picture itself. Since not all browsers display exactly the same, I had suggested testing across multiple browsers. I find that IE has more of a "smudgy" look.

i've tried firefox, IE and chrome, FF seems to be the worst and itr's slightly visible in the others

I would expect a slightly different view across browsers. Tried from a different computer to rule out your video card/monitor? Do you have this online so that we can access it directly?

I dont see the relationship between CSS and smudging.

your Monitor is geting old...
time to replace it.
ps there's nothing wrong in the given screenshot

I also don't see anything wrong with the screenshot??
