Hi,

i refine the bug preconditions:

The bug:
-define a combobox subclass with:
- PictureSelectionDisplay # 0
- value = None or 0 Important it is that the Value = is written on the Properties list of the VCX

Now:
- define a container,custom,page vcx subclass
- drag the combobox subclass on the container
the combobox is not visible
change Visible property of the combobox -> it is visible

This occur if the combobox parent object is a container,custom,page object;
this problem not occur if the combobox parent object is a form.
