How about this, off the top of my head, not tested:
on mouseEnter -- in the card script
  get the name of target
  if it contains "group" and the number of target = number of groups then
    -- do stuff here
  end if
end mouseEnter
Unfortunately, that doesn't seem to work. It looks as though group controls 
don't receive either mouseEnter or mouseMove messages (in their own right - 
they do receive them when the target is a control within the group).

Depending on how many groups you are likely to have you could do something 
along the lines of

on mouseMove
  get the number of controls of the target
  repeat with x = 1 to it
    if the name of control x contains "group" then
      if mouseLoc() is within the rect of control x then
        put x & cr into msg    -- do your real work here
      else
        put "" into msg
      end if
    end if
  end repeat
end mouseMove

I create groups on the fly. I want to be able to tell when the cursor is 
within one of them (so the user can move the whole group). It seems that 
a group only knows the mouse is within it if the mouse is over one of the 
*objects* in the group. If I turn on the group border, I'd like to know 
that the mouse is within the groups border whether it's over an object in 
the group or not.

I know I can test to see if the mouse is within the rect of the group, 
but this only works if I already know the group's name. What I'd like to 
be able to do is move the cursor over any part of the group (anywhere 
within the group's rectangle) and be able to identify the name of the group.

Does anyone know how to do this?
