IE8 - Lost background color

I'm trying to solve a problem and thought I'd ask to see if anyone else encountered this.  Here's my problem... I noticed that the #pcMainArea lost it's background color in IE8 and Firefox, but is fine in IE7.  Here is the css code that I'm using, it's nothing fancy, mostly unchanged from original.

 

#pcMainArea08 {
   width: 900px;
   background-color: #FFF;
   margin-left: auto;
   margin-right: auto;
   margin-top: 0px;
   margin-bottom: 0px;     /* spacing between main area and footer */
   /* border: none; */
   border: 3px solid #CCC; 
  }
 

After trouble-shooting this, I added a border statement (last line in code) to see what would happen.  It worked fine in IE7 but IE8 doesn't seem to recognize the space, the border was placed between the #pcMainArea  and the #pcHeader.  That would make sence as to why there is no background color.

 

I tried everything I could think of, removed the footer.asp, checked css puncutation, etc.  Still no background color.  I researched this on the internet and found hints that it may be a problem, just haven't found any resolutions.

 

I would greatly appreciate any help on this issue.

Thanks!
