1. Enter a name in the name field
2. Enable Inspector
3. Try typing into the field while Inspector is focused on the particular field
Forgot a step. With Inspector enabled, focus/select on a separate field, and then try focusing/selecting back in the name field. In that case, one is unable to focus back to type in the name field.
It seems to me that perhaps you shouldn't be able to type into any fields while using the Inspector.
Looks like this was fixed by bug 642471
