shared group loses buttons & scripts when changing cards

[Dr. Hawkins]

I have a group in one of my stacks that the user will never see for
maintenance.  It has a slider to slip through pieces of forms, and a couple
of maintenance buttons.

I tried to change a script on a button a couple of times yesterday, and it
kept going back to the prior form, or even *using* the prior form (some of
this seems related to switching cards).  If I open the script, I get a *new*
tab in the editor, even though the old tab (with the revised cod) is live.

Today I tried deleting the troublesome button--and it comes back when I
change cards.

sharedBehavior and backgroundBehavior are both true for this group.

Is there a property that should account for what I'm seeing?
