[OS X TeX] Displaying PDF in TeXShop

[André Bellaïche]

Hi,

In TeXShop, when displaying the PDF typeset file on two pages side-by-side, the pages are separated by a grey strip.

As I would like to display one large image on two pages, and be able to judge the effect, it would be better to have the width of this strip reduced to zero. I suppose this width is  parameter of TeXShop. How can I change it?
