vertical scrollbar and page layout

[joe panico]

Hello,

Whether or not there is a vertical scrollbar visible in Mozilla effects 
the available page size and therefore the page layout.

IE always diplays the runway for the vertical scrollbar, whether or not 
the scrollbar itself is displayed, which means that the available page 
size is always the same.

I would prefer to have the IE approach, because in Mozilla you get 
annoying page re-layouts as you traverse a series of similar pages that 
differ mostly in just the presence of vertical scrollbar.

Is there a way to force Mozilla to display the vertical scrollbar (or at 
least the runway for it) using Javascript or some other "content" based 
method?

thanks

joe
