Double clicking promotes the selection to the component.
If the component includes the root, it cannot be moved.
What is happening is you are double clicking to select the whole thing, and it's including stuff that is at the root, which cannot be moved. So when you invoke Move, the selection is cleared because it is invalid.
Try this:
- In a new file, make a box primitive as a component.
- Double click to select it.
- Invoke Move.
- This will work.
Now, drag the body out of the child component body folder into the root component node at the top of the browser.
- Do the test again.
- It will clear the selection on Move, because the body is now at the root, and double clicking promotes the selection to the component, i.e. the root. (which cannot move)
Let me know if you have any other questions.
