Changing position/dimensions of a control that is part of a group

As Mark Weider said, control ids are unique, so there is no need to 
specify the group, in
    ... graphic id 1234 of grp "unneeded" of ..

However, the same is not true of names, so it's perfectly possible to 
have multiple graphics (or multiple groups) within the card, each with 
the same name. It is therefore ambiguous which of them is being referred 
to -and unfortunately the engine does NOT inform you of this ambiguity 
(and hence possible bug).

So - in your original example here -

  set the width of graphic "BaseControlsBkgnd" to item 3 of tCardRect

are you sure there s no other graphic with the same name ?  (- NB it can 
be anywhere withing the stack file)

Ir would be better practice to say somethingglike

  set the width of graphic "BaseControlsBkgnd" of grp "wherever" of grp :to item 3 of tCardRect
