Cannot reparent window to suggested parent.

Hi,

I am stuck with a error message and a behaviour I can't understand while creating a UI of nested windows.

The error message is

Cannot reparent windows to suggested parent. Window will not automatically close. UnityEngine.GUIUtility: ProcessEvent(Int32, IntPtr, Boolean)

The strange behavior is that I cannot edit manually the values of the UI objects in the inspector. I cannot modify the values with the keyboard, but I can modify them with the mouse by clicking, holding and moving to the right or left

This happens when I try to create a scrolllist within a UI, but I can't find a way to reproduce it all the time. I also cannot find a way to get rid of it when it happens, except deleting UI elements and restarting Unity.

Any idea where this is coming from ? I am not using anything besides standard UI elements

 

Hi ! Did you find a solution? I am also stuck in the same error

 

Do you get the solution i'm also stuck with that same problem, and I don't why it's not taking my any input if I want to rename something I'm not able to rename It or even if I want to change numerical value I'm not able to enter it Please if you get the solution please reply

 

Just Restart Unity, THEN it will work.
