Selecting an entity via the list does not always select the object, clicking till blue in the face does not select anything.
Selecting an entity by clicking on it does not always select or respond in any way. Clicking until blue in the face does not help, entity decides if it will be selected or not.
Summary: Selecting objects is very hit and miss. The click does not seem to be responding .
