I've some bad effects when expending folder in left column of script editor.
OS : macOS Sierra Version 10.12
FileMaker : FileMaker Pro Advanced 126.96.36.199
Sometimes when expending folder where I gather scripts the list is cleared, replaced by a white area and I can't select a script. When closing the folder, the white space below the name of folder is left and not reduced.
When I leave and starts again the editor of scripts, the expansion or the closing of the lists is correct. It is degraded in time.
Perhaps it's a bad effect coming from macOS Sierra ?
