Editing button scripts

[dsquance]

I have been away from Rev for a long time--used versions 1 and 2, and have just obtained version 4 (studio) to check out. I have a simple project with a couple of stacks containing cards with shared buttons. Unless my memory is faulty, I could edit a button script in a shared button and it would change all the cards containing that button. Has there been a change in this behaviour? And is the best way to do a global change of this nature to script it through the message box? That seems cumbersome to me for a quick adjustment.
Thanks.

I think I may have stumbled upon the answer. Clicking on the group button in the menubar while the script is active seems to have worked. Doing it before the script was active made no difference. Does this sound right?
