I was afraid of that. Sorry to pester.

It is much better now. The sizes are not quite the same, but I cannot 
*see* anything different between them.

The creation dates are all different, of course.

The fonts?? are different (there is likely a counter not being reset, 
and this may not matter):

pprint1.pdf has:

/Font << /CLF104 10 0 R
/CLF103 9 0 R
/CLF102 8 0 R
/CLF101 7 0 R
  >>

pprint2.pdf has:

/Font << /CLF108 10 0 R
/CLF107 9 0 R
/CLF106 8 0 R
/CLF105 7 0 R
  >>

More interestingly the the compressed code has differing lengths:

pprint1.pdf has:

<< /Filter /FlateDecode
/Length 3028
  >>

pprint2.pdf has:

<< /Filter /FlateDecode
/Length 3027
  >>

I have no idea if this is significant, for all I know something 
insignificant like the creation date, or I suppose the different font 
numbers, may be in the compressed data and accounts for this 
difference.

Anyway, this is is *much* better. It is *so* much easier to see the 
results of my mucking about :-)

Thanks Marc.

Cheers,
Bob
