it must be the application process splash window. there was a bug in v13 where the window size got messed up.
go to database settings, interface, and make the splash window visible if not already. I assume this is mac; when you “show all windows” you should find that the square is a window title bar 1 pixel wide. when you click on it, it should become a normal window. ********************************************************************** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
