Facing Pages in InDesign

Go to Document Setup and uncheck Facing Pages.

Also...

1. Open a document that has been created as a facing pages document.

2. In the pages panel menu, choose Allow Document Pages to Shuffle (CS3) or Allow Pages to Shuffle (CS2) (this should uncheck, or deselect this option).

3. Grab the right-hand page of each spread, and pull the page to the right of the spread until you see a vertical black bar appear and then release the mouse. This will separate the page from the spread, but the page will remain a right-hand page.

Quite possible, I no longer have InDesign, but I think Document Setup and uncheck Facing Pages might be the answer.

Ask Adobe. That's not an Apple product.
