I'm in the process of switching from my PCs to my Mac. Everything is going great, except I'm having a problem with dreamweaver displaying pages correctly.

I originally designed the page using Dreamweaver on my PC, and now I want to edit that same page using Dw on my Mac. If you go to http://gseador.com, that is how the page should be displayed. Notice there are 3 columns. when viewing that same page (index.php) in Dw, the Recruitment column appears on the left side of the page under the welcome section (as can be seen in the screen shot I included).

Any suggestions, thoughts, or fixes you could send my way would be awesome. Thanks!
