Cannot manually select objects for List or Array variable

2.2 on Mac.

To reproduce:

1. Add some objects A, B, C
2. Add variable V of type Object / Array or Object / List
3. Try to add A, B, C to V - won't accept (can add ground, light, etc. fine)

Adding A, B, C, to V programatically works fine.

I am having the same problem.
Trying to do tutorial 7.1 and can not add any of the skaters to the List of Objects.
I have not tried to add them programmatically however.
Thanks for the suggestion of the work-around.

I do not have the same problem on windows. Is this a mac only problem?
if so I am sorry.

By following 1,2,3 I got a varible that did allow me to add items.

And can you not?
1. add items.
2. while making varible add list thn add the items to V
