edit: sorry i’m not sure it will work because it looks like i havent unregistered the callback, in fact disable_event is wrong

wow, this works! not sure, why do you think disable_event is wrong?

also what this about ::? I’ve never heard of it

fn disable_event = (callbacks.addScript #selectionSetChanged "check_selection()" id:#m3dLearnEvent)

should be

fn disable_event = (callbacks.removescripts #selectionSetChanged id:#m3dLearnEvent)

i guess the :: is because you didn’t declared the rollout before the function is called.
i use the :: to call a function from a filein .ms so i tought is a kind of a “lookaround for this parameter” feature.

not sure but it seems like it worked…

let me know if you find something about it!

it seems like it is working. thank you very much.
I didn’t know about this :: anything before. in fact this my first attempt to make script properties manipulations at startup. thanks again
