I’m sorry. I was typing the website URL incorrectly from the screenshot. It’s createAwebsitequick[.]com.
But your site is looking good in all browsers on my end. I’ve honestly never had anyone tell me the portfolio section does not work on the homepage, and we’ve been through a lot of support and buyers. There were a couple of people in the past, but it was the browser-zoom thing.
Looks like your screenshot is in Chrome on Windows 7. This is as close I can get to re-producing the same environment and I can’t reproduce the issue. See sreenshot: http://i46.tinypic.com/xm5o90.png
