Layout question relating to screen size/open office writer

[Whoojeedoo Monster]

I used to have a smaller screen, and when I did the OpenOffice writer program 
would display the pages as centered in the middle of the grey space with the 
next page directly beneath the previous, sort of lined up in a collumn.  Now 
that I have a larger screen it displays like this instead - not using the 
centre exactly, either a blank space at the side or two pages side by side.  Is 
it possible to return the layout back to the previous one without changing 
screen sizes?
