I am running v9.2.4 190621 on a MacbookPro on Mojave 10.14.6. In the Button Settings window I am unable to use any of the drop-down buttons to change the number of boards on each button page. In fact none of the drop-down options on either Button settings or Live settings respond. You click on the drop-down but nothing happens so you can't change from the default number. I'm sure this happened to an earlier version and was fixed but it's happening again. I have tried the latest fix file but that didn't help.
Thanks for checking. I have a second MacBook also running Mojave and it has exactly the same problem. Strangely the Button font size drop-down works perfectly but done of the others on the Button settings window. I have an old Windows 7 laptop and that works fine so I can export any shows that I need to change the board numbers, make the changes then export back to Mac but obviously this is not particularly convenient!
SOLVED Happy to report that when I tried to make some changes today following an Apple O/S update all drop-downs now work perfectly. Clearly it was nothing to do with the Lighting Controller application
