MdiForms- Form positions

I have a MDI parent form on which I have placed a picturebox control with three buttons on it. I am trying to create toolbar but with 'big' buttons.

However whenever I load a child form the child form is always behind the picture box. Why? How can I make the child form sit opntop of the picturebox?

I'm using VB6 SP3

Try right clicking the object and click on either Bring to Front or Send to Back.
