Resizing content of a group

[jbv]

Suddenly I have a blank : I have a group made of several fields,
and would like the content of that group to be resized when the rect
of the group is modified...
I tried several combinations with locklocation of fields and / or
group set to true or false, I looked for a property that can do that,
I searched the MC archives, but didn't find anything...

Any suggestion ?

Thanks in advance,
JB
