Thank you for your post.
I am unable to replicate the issue using FileMaker Pro Advanced 14.0.5 under Mac OS X 10.11.4.
A Container field formatted for Interactive content is the same as a WebViewer. That is, FileMaker Pro is using the OS WebKit to display the information. Since I am unable to replicate the issue, I believe the issue may be caused by the Adobe Internet plug-ins. Try removing the following two plug-ins from: [Your hard disk] -> Library -> Internet Plug-Ins
Reboot and see if the issue continues.
Your very first suggestion fixed it! You're amazing.
Working perfectly now.
Thank you very much for your incredible support.
I am having a similar problem. I was logging in to Windows as THill. When I open my solution which is PDF images in container fields, I can see the image.
We are moving to user ID by job title, so when I log in as AP, I see a blank field except for the Adobe emblem. I am using FMP13 on Win10.
