I load three PictureBoxes (Win1, Win2 and Win3) onto one form.
Win1 is large and the other two are small.
I can then draw on Win1.
I can then use .TOP, .HEIGHT, .BOTTOM and .WIDTH to place Win2 on top of Win1 and print on it.
I can then use .TOP, .HEIGHT, .BOTTOM and .WIDTH to move Win2 back to it's original place and size.
I can then use .TOP, .HEIGHT, .BOTTOM and .WIDTH to place Win3 on top of Win1 and draw and print on it.
Next I would like to place Win2 on top of Win3 and again print on it.
But, when I use .TOP, .HEIGHT, .BOTTOM and .WIDTH to place Win2 on top of Win3 I can't see it.
It is again on top of Win2 and I have to move Win3 before I can see it.

How can I see Win2 without moving Win3?
