For some reason when I refresh that pages. Or do a /dev/build on my site. The css background images are disappearing.
The layout seems to be fine, it is just the background images that are linked in my css file, one minute they are there
and then I refresh or dev/build and they are gone.

I REALLY REALLY NEED TO FIX THIS PROBLEM. Please help me.
I thought that it was a problem with my browser, but for some reason I do not know how to get it back?
Has anyone else had trouble with this?

here is the link to the site:

http://www.mustangandclassics.com

The problem with the template is that I was directly linking to the css files in my template

Like This:
      <link rel="stylesheet" type="text/css" href="mustangclassic/css/layout.css" />
      <link rel="stylesheet" type="text/css" href="mustangclassic/css/typography.css" />
      <link rel="stylesheet" type="text/css" href="mustangclassic/css/form.css" />

My CSS files were doubling up whenever it would process the page.
SilverStripe was choosing the first available layout when it would load.

I deleted the direct link to the css above and replaced it with this:

      <% require themedCSS(layout) %>
      <% require themedCSS(typography) %>
      <% require themedCSS(form) %>

Of course the only way that this works in this instance is if your css files are named exactly as above
Example
layout.css
typograhy.css
form.css

Thank you very much for your help!
