I tried the restart and it sorta worked.  The menu will scroll through the list and "body parts" allows me to choose individual parts and "body" the whole body, but props, camera and lights all show the body parts list.  Also, the pull down menus for camera and lights on the left side of the screen won't open until I click on the UI dots arrow.  Once I do that they open and the camera one works but the lights can only be selected by clicking on the ball icons.  I'm beginning to think this application is haunted!
