I had been viewing all the pdf's in container fields without any difficulties on my Mac. I downloaded and installed Adobe Reader this morning because I needed a feature that wasn't in Preview. I opted out of the request to make Adobe Reader the default pdf reader on may Mac. But now, when I open FileMaker with a container field that has a pdf, it displays it using Adobe Reader instead of Preview. Where can I change this option? Does it have something to do with brower plugin options?
