After intalling 8.6, I experienced consistent problems with a PageMaker document which contained an imported Illustrator EPS image.
I was unable to create a PostScript file every time, with PM quitting predictibly.
The same process worked fine on an 8.5 machine, as it had on mine before 8.6.
Not sure if the problem is with the 8.6 PS driver, PPD, PageMaker, what....?
Tried different PS drivers (8.5 LaserWriter, Adobe PS, ...), saved different versions of the Illustrator file (v.6.0, 7.0, 8.0).
so it goes....
