We have discovered a bug in the FileMaker 15 Script Workspace (running on OS X 10.11.5):
1. Open remotely a FileMaker 15 file that is hosted on FileMaker Server 15.
2. Open Script Workspace.
3. Double-click on the name of one script, so that it appears in the script workspace.
4. Close the script workspace.
5. Close your file.
6. Re-open your file.
7. Open script workspace.
8. BUG: The entire left margin area is gone.
