Lynn,

Just to clarify I think this is actually very significant. Versions 1-5 of
Acrobat always displayed at 72dpi this gave us a cross platform format in
that an image created at 100% 72dpi would appear smaller on a pc in terms of
screen mm which is correct. Now I have just checked distiller 6 and the PC
distiller defaults have been changed for "Screen" to downsample to 100dpi
whereas on a Mac its still 72. 

This will result in 

All legacy pdf's created on either platform, off which there must be
millions, will appear larger on a PC with V6 and any 72dpi downsampled
images will be lower quality. As will all future pdf's created with V6
defaults on a Mac. Furthermore files created on a pc with the new defaults
will be larger.

Not really a step forward I would say. I have now scrapped the idea of
moving to V6.

Regards
Paul

You are talking about two different things here. Your monitor resolution is 
a fixed number like 72 ppi or 96 ppi. (Used to be that Macs displayed at 72 
ppi and PCs at 96 ppi, don't know if that is still true). 1024 x 768 or 115 
x 864 is the screen area displayed, it is not really the screen resolution. 
The Acrobat setting applies to the resolution not the screen area. If 
Acrobat 6 is set to use system settings it reads what your monitor 
resolution is and uses that, it's not overriding anything. If Acrobat 6 is 
set to use a Custom setting then Acrobat is overriding the system settings.

Hope that helps.

Lynn
