I know you are working on display behaviour of control... but from version 188.8.131.52 I noticed below problems:
1. To show controls in proper order in diolog I need to reverse control order in Editor.
1. using control changes displey order - the control is moved on the top
2. after loading dialog when I move mouse pointer above Picture Box controls they change display order
3. loading image to Picture Box moves it on the top
border of control stay in the right place but content changes order.
