VB.NET Picturebox on top of MDI Child

Question

Any idea why a picturebox in a MDI parent would show on top of a MDI child? (even when MDI child = topmost)

When calling picturebox.SendToBack the picturebox disappears

Answer 1

What I did was, created a borderless form with the picturebox on it, and threw it on the MDI parent as a MDI child, seems to do the job!
