Who knows really? I used to work in R&D for HP (past lifetime). Got to 
 doing a LOT of electrical connector tests, esp gold plating 
environmental. I'm not a statistician, but I had a class or two, and 
was assigned one for much of my endless testing.

One thing I learned was that numbers can be operated on so that you 
just can't believe them. They can be made to say anything, just about.

If we see a tiny difference in the histo numbers it could mean a big 
OR insignifigant change in the data sent to printer. If we see a huge 
change in the histo, depending on how it is calculated, and how many 
points it is based on, and how it was origianlly skewed (dark or 
light?) it may mean a small or large change as well. Then there is the 
question as to how sensitive is Paul's workflow to changes in critical 
parts of the data (ie 3/4 tones maybe), and it's time to take a couple 
of asprin<g>. About the only thing I'm prepared to say right now is 
that there IS a change. I can also say I'm puzzled by my test prints 
here. That's safe to say<g>.

I want to believe I have something not set right in PS7- after all 
that would mean I could start using it again. Maybe that radio button 
or drop down box will turn up soon. Right now, time is a problem and 
I'm low on ink, so I can't run many more tests myself. I do want to 
thank everyone who has helped me so far in trying to resolve this.
