Thank-you for your well thoughtout reply.  I tested images and modules to see if they were causing the problem. I created blank test pages and worked on the code testing the parameters of the display setting. The designer told me not to delete any of the lines below. If I understand you correctly keeping the first line may be the cause of the problem.

.template_style{width:980px; margin:0 auto;padding-bottom: 5px;}

.template_styleWide{width:90%; margin:0 auto;padding-bottom: 5px;}

I think things are working better now  -- one of the fixes was to change the display setting on the old monitor to the next level above 1024. Overall the site does look awesome. The admin at my school was speechless when she saw the site. Not often happens. :-)  As would have it when things start moving well along a new display problem has cropped up and I am at a loss. i created users for the site. When I logged in as one of the users the home page suddenly stretches across the screen as wide as can be. Just the opposite of the original problem when the display moved right and a large black area was on the left.  The rest of the site displays normally.  Hope you can help. Thanks in advance for your help.

I understand that the skin resizes to a larger size when in edit mode.  BUT

My site looks great on my home computers except for an older 17 flat screen. I tried the site on  the computers at school, family etc. The site stretches to the right whether I an using a package skin or the DNN skins. I tried editing the CSS. It did not fix the stretch to the right problem, if anything it made the matter worse. Everything gets bigger. I am at a loss.

I am using DNN 5.1  and Navigation Suite 1.4.6 (All in ONE Menus) & Skins -- the colors are awesome and the site has the look I was going for in the design. I don't want to change packages and I don't think the package is the problem because the same thing happens no matter what I am using.  The package designer has given me a few suggestions for the CSS -- very standard according to everything I have read.

What am I missing here? Something in the installation? Did I select an install variable incorrectly? Has anyone else experienced this problem? Shoud I try a few more packages to see if one works. That can get expensive! 

School starts in 3 weeks -- got to get this resolved! Running out of time.  Running out of ideas...

You appear to have included some images above, but they are not displaying.  From your description I am unable to picture the problem in a way that I can suggest a solution or direction.  Can you please provide a link so I/we can see the site and get a handle on the issue(s) you are facing?
