In normal use, it works fine.
Maybe not really a bug, just setting button invisible need right timing?
(A). I put "go to layout2" under "set button invisible", invisible not work.
(B). I set button invisible in starting of layout2, not work.
in (A), set invisible, wait 1 sec before go to layout2, works.
in (B), if the event is not "start of layout", works.
In Chrome & Firefox latest ver.
