I totally get that (and good to hear about the change - basically when poss ctor and dtor functionality are mirrors)

But what I meant is thanks to you correctly guessing I had an unpacked CoreRPG of Yore in my directory (March), that’s why the Options callback was still double. I wondered if you also did something since March on the onClose() since I never noticed ANY onClose() printouts or errors for sure prior to my removing that older CoreRPG pack.

Was curiosity, no answer needed as both are working fine now for me. Was all self-inflicted
