background behavior questions

[JohnRule at aol.com]

I have some questions about background behavior:

Can I apply background behavior to anything (i.e. a field, a button, etc.)? 
This works very well on a group, but I could not seem to apply this to a text 
field or button.

If I delete a group (or object) that was 'common' to all cards, and then I 
want to put it back, is there a way to get it to 'sync' up with the other 
cards?


Thanks,
JR
