After working with a file with many PDF files in a container Filemaker becomes somewhat unstable. The first sign is that PDF files stop appearing in the container. Continuing usually causes a crash. Restarting Filemaker shows a very different container with lots of PDF editing and conversion options. See screen shot. I have never seen this display regardless of the container settings. It might be a great option but not as the result of Filemaker crashing. I have a filemaker database for a non-profit with over 200,000 jpeg files that never crashes. On my mac pro using FM 14 last release I have frequent problems with files displaying PDF images with only a few hundred externally stored images.
