I have had no luck in getting Microsoft Word or Excel on a Mac to launch by double-clicking on the file icon in a container field. I have tried with the container optimised for both interactive and images but to no avail. I have also tried inserting the file from the menu, by double-clicking and by dragging it into the container with the same result. I have not yet had the opportunity to see if this problem also exists on a Windows machine.
Interestingly, if I access the database on an iPhone or iPad using Filemaker Go then the option to view the file works.
I have looked at the Content Management solution and can see no difference in the container options
