-edit- I dont need the answer anymore now that i calculate based on mousedown position.
Basically in relation to this question It seems like e.X,y and e.Location.X,Y is relative to mousedown? I seen negative values when i havent moved it left/above the parent picbox.
So it seems like the values are relative to my mousedown, but i need values relative to the parent because i update the left/top every event and other datat and relative to mousedown is breaking my code.
