Hi Gary I've got Fm 9, 8, 7.2, 7.0 and 6, all on the same computer (XP, SP3). And sometimes, I've got multiple versions running at the same time. No problems here.
Just make sure you test Save as/Print to PDF. This may be a problem, depending on your version of Acrobat. Cheers -- Yves Barbion Adobe-Certified FrameMaker Instructor www.scripto.nu
