Did you install the recent OSX updates right around the time this started happening?
Yes, I've had similar issues, with Mac and Windows, esepcially outside of the LAN, but even there. I haven't been able topint point the cause or solution.
AdobePDFViewer is possibly the culprit. I deleted it from my Client(s) and suddenly PDF documents started showing again in FMP13. It seems FMP13 and the AdobePDFViewer 9/9.5 don’t work well together. I’ve heard, but not tried, that Adobe Reader XI (V11) works better.
Path to file:
MacHardDrive/Library/Internet Plug Ins/
Is that true as well on Windows? I thought this file was needed on Windows client as it is the intranet plug in Filemaker was using.
When you delete this file does Preview become the default viewer rather than Acrobat on the Mac?
Ok this is truly weird so I'm not sure exactly what solved the issue but it seems to be one of two things:
1. We installed the latest pending security updates
2. We rebooted the server
After these actions the issue was resolved!
