Thanks Miles Ahead. I am torn between wanting to keep on using the old 16 bit software which contains all my business and personal contacts but then needing to install a second operating system. Since I am not that proficient and new to Vista, I would be worried about screwing something up. I do have an XP disc but again, I would be concerned about crashing. I tried exporting all the contacts to Outlook, but the fields are all different and it doesn't seeem to have the capacity to let me use overall categories and sub-categories for my contacts. i.e. I have a section for "Personal Business" and then within that category, I have subs like "Contractors" "Doctors" etc. Can Outlook do that in Office Seven? Or is there some other software I could export everything to? I have read that ACT is no good, especially the new one. I have the same problem with Calendar Creator which I ran on XP. I think it is 32 bit, but it still won't run on Vista. Any suggestions?
