How to use an item on the main character?

Hi guys,

tick the checkbox for your use command that allows interaction on own character.

Thank you Sebastian. But it's not working mate. In the command properties of Mouse (In interfaces) . I selected my "Action" in Buttons Tab which is my  main cursor and in it's "Command Properties" I checked "Own Charactert" but it didnt make any difference mate... 

is it 3D?

Yes, it's a 3d character. So it doesnt work on 3d characters?

I don't think so.. I seem to remember it being fixed but not released yet, I could be wrong
