Resume from suspend - all programs are closed 12.04

I'm using a Macbook Pro 6,1 and have jumped through a few hoops to get to where I am. I finally have a working system, but there's one thing I haven't been able to find a solution on. When I close my lid on my Macbook it goes to suspend mode. When I open my Macbook again it wakes and goes back to my desktop. Only problem is it won't load the windows I previously had open. It's as if I logged out instead of my computer going into suspend. Is there any way to get my programs not to close when I close my laptop? I have the latest Nvidia drivers installed.
