Oracle Express Objects: Bugs & Heeelp! *jlm*

I've found these problems in Express Objects (vs. 2.0.2 under Win95). Might anybody tell me if they're known bugs and if exist any ways to overcome them?

1. DIMENSION LIST BOX (dlb) -------------------------

For instance take a Nation/Area/City hierarchy:

ITALY

  |--NORTH
  |    |--Milan
  |    |--Venice
  |--MID
       |--Florence

I'd like to move 'Florence' from MID to NORTH. I use these Express command:

   A1.PARENT(GEODIM 'Florence')='NORTH'
   XP_DMHIERCALC GEODIM 'STANDARD'
(where GEODIM is the dimension name and A1 is given
 by Express when installing the dimension)

When I call the RefreshListBox method after having modified the hierarchy, the listbox collapse the indented hierarchies, but when I re-open them, the dlb contains occurencies in erroneous places, in wrong hierarchies (re-collapsing and re-opening solves the problem, but it's not so nice...).
Do you know how to solve the problem or how to modify a hierarchy in a different way?
And is it possible to indent the levels a bit more than default value?
(i.e. enlarge the indentation)

2. LIST BOX (lbx) -----------------------------------

As reported by anybody out there, list boxes often automagically grow... Every time I open a form some 'ghost' modify its dimensions. Any update?

Whenever I'll find any other bugs, I'll try to post
them asap.

Thanx for Yr attention and help,
