Re: Mixed Page Orientation

I've just done this in Adobe Acrobat X Pro, and it's really very simple

1. Make sure the Tools panel is displayed.
2. Select the page that you want to rotate, and then click Rotate.
   This displays the Rotate Pages dialog box.
3. In the Page Range area, simply select which pages you want the orientation to affect.
   You can specify the page, all portait, all landscape or a combination.

let me know if you have any problems and I'll try to help
