[OS X TeX] Multiple-page editing

[Alain Schremmer]

I am doing a lot of editing these days in TeXShop Version 2.18-svn  
(2.18) and the fact that, every time I typeset to check what I have  
just done--which is very often, the multiple-page display jumps so  
that only ONE page is displayed is getting to be a little bit more  
than a little bit of a bother.

Is there a viewer that would hold a multiple-page display still as I  
typeset from TeXShop that I could use with a minimal amount of  
tinkering in TeXShop?

Hopeful regards
