I used to thing that do. But I am sure it isn't:
- Delphi does not fall back on the parent neither (ok no proof...)
- It would not make sense: put a TEdit (crDefault) on a TPanel => then 
the edit would have to follow the panel, but it wishes to show the IBeam 
still.

And about screen cursor. It is not a fallback for default. If 
screen.cursor is set to none crDefault, it overrides all other cursors 
(at least thats the windows implementation of the LCL.
