Folks, 

FM6, W2000, Acrobat 5.05. I regenerated a long manual I've been working on for some time and re-distilled it. This was after adding some text and changing some graphics to fix errors I found. 

Well, I hit the mother lode on G errors, and this time they are FOR REAL. 
In the resulting pdf, Page 1 - 107 look fine, but pages 108 - 148 look like the Distiller thought I was printing to something much smaller than my default 8.5 x 11. That is, the top and bottom and left and right margins suddenly became much larger, so I no longer had headers or footers or a lot of my text at the beginning and ends of lines. I suspect this cutting led to a lot of the g things. 
The rest of the book did fine. 

The bad stuff, of course, is in the chapter where all the G stuff said it was. I saved it to MIF and looked up some of the numbers. Most seemed to be associated with Heading 3s. But not all heading 3s had problems. I never did find the one associated with the first bad page. 

I looked in the FrameMaker and everything looks great. Page 107 has a plug-in card description and that card's graphic. So does Page 108. 

I redistilled it, and got the same results. 

I also tried just distilling the chapter and got exactly the same list of errors. 

Help!
