UserControl: Frame with Transparent Bkgd

I am trying to make a Frame with a transparent background, if i use a regular frame, it hides the backgroud images of my form (i'm using a skinned form)
I tried creating an empty usercontrol and setting its ControlContainer property to True, and it works, but it behaves funny when i set its background style to Transparent, some of the controls i paste inside it dissapear!!!
when it's not transparent, i can see those controls.
any suggestions?

That may have something with the ZORDER method of controls. Look in MSDN help for explanation. Pay attention to the last paragraph or so. It explains the pecking order of controls when they overlap
