Visual Studio 2008 Absolute Positioning

I'm trying to turn on absolute positioning for an internal web application I am desigining in Visual Studio 2008. It's a brand new project, went to Tools->Options->HTML Designer->CSS Styling then checked the "Change positioning to..." and it seems like it's going to work. When I drag a control onto the designer I can move it but as soon as I stop moving it, I can no longer move it in an absolute fashion. When looking at the code, the css is added to the header (as it should) but when moving the control it just creates <p> </p> tags. Am I fighting an uphill battle here, and this is just how it works? I would assume you could reposition controls after adding them.
