Hi Vanessa!

First: wow, thanks! I need to use the menu item of the halo more...
will do that!

Second: I've tried the "debug action invocation" option in the halo
menu for this menu item,

  World -> new morph... -> from alphabetical list -> L-N -> LineMorph

and when I clicked "proceed" in the debugger I got exactly the same
error as before, i.e., this,

  UndefinedObject(Object)>>doesNotUnderstand: #hand
  TheWorldMenu>>newMorphOfClass:event:
  [] in MenuItemMorph>>invokeWithEvent:
  CursorWithMask(Cursor)>>showWhile:
  MenuItemMorph>>invokeWithEvent:
  MenuItemMorph>>doButtonAction
  [] in MenuItemMorph>>debugAction
  [] in FullBlockClosure(BlockClosure)>>newProcess

because the argument "evt" in TheWorldMenu>>newMorphOfClass:event: is
nil... but if before clicking on "proceed" I change evt to a CR, then
I don't get any errors, and the LineMorph is created.

Do you think that one of these two methods should be changed?

  TheWorldMenu >> #newMorphOfClass:event:
  MenuItemMorph >> #debugAction

(I am just a newbie 😶)

  Cheers,
    Eduardo
