Hi , somehow in this patch the select and iobox get vvvv to freeze. i upload here in case you find something.
Creating and iobox from zero does not créate this behaviour. I simply copy and iobox from the help patch of setmatrix and made it to be toggle and connect to the select.
the iobox shows 1 but in reality it has the values of 99999999 (enable “show value” in inspector). so no doubt selecting 99999999 pretty stresses the patch
