macOS High Sierra
iMac (27-inch, Late 2013)

FileMaker 16 Pro Advanced 188.8.131.522
When running an application in full-screen and I open the script workplace, the IntelliSense does not work. If I exit full-screen and then use the script workspace, it works as expected. This has happened on both my iMac and my MacBook Pro since I upgraded to High Sierra. It behaves this way with, or without any plugins enabled.
Also, sometimes when the Script Workspace is no longer the active window, the scripts pane on the left goes black.
