Thank you for your post.
I was unable to reproduce this issue on Mac OS X 10.10.5 or 10.11.3 when Minimizing a Word Document while a FileMaker Database Window is in the background. For troubleshooting:
-What version of FileMaker is she running and is it up to date? (FileMaker Pro 13v9, FileMaker Pro 14.0.5, etc.)
-You might try a New File (perhaps from Starter Solution)?
-You might have her try this on a new user?
I look forward to your response!
She has 13.0 installed. When I suggested she go to "Check for Updates" it told her that 13.5 was available but when she clicked on the link to FileMaker, there was no update for 13.5.
