[Gambas-user] Proper use of containers

[M0E Lnx]

So I'm trying to put all my objects in containers for easy handling of
window resizing, but I've ran into a problem.

Here is the problem.

Hpanel1 ( expand=true)
 |- Frame1 (expand=true)
   |- Hbox1 (expand=true)
     | - Textlabel1 (expand=true), |- Combobox1 (expand=true)

the frame resizes just fine, which tells me the Hpanel is resizing fine.
but the Hbox which is a child to Frame1 does not resize. 
I'm using gambas2-2.12.0
My app uses gb.gtk

I've noticed that when you use more than 2 containers, there are
resizing issues. 

Has anyone seen this? or can anyone suggest a better
approach?.
