For the first time in many years, I opened the help window. Whatever I do, after I close it, it automatically re-opens itself. That is, if I switch to another application, hide ELAN, whenever I get back to ELAN, the help window is open again. Rather annoying, and never happened to me before. Can’t say it immediately started after installing 5.9, but like I say, it never occurred before.
(ELAN 5.9, latest Mac system version)
