Where is Pallas ?

[carlomuccini]

Hi

Let's say I "deleted" all the asteroids from the list: 

    MENU / Data / minor planets / Clean up Delete / Delete All Minor Planets

but it doesn't delete them all, about 47 remain

   

If I select an asteroid among those remaining, e.g. Urania and press DEL

   

asks for confirmation but doesn't delete anything.

I wonder if and how it is possible to completely empty the asteroid list and then reload them from MPCORB for example

Thank you

Carlo
