Problem Description

Suddenly the Clip Volume cannot be modified or edited. The green and blue arrow handles used to modify the clip volume are not shown or available. The white rectangular section clip box is displayed but clicking on this has not effect. The same Clip Volume can be modified when opened on other machines.

Steps to Resolve

1. Clicking on the white rectangular section clip (image 1 below) should show the Clip Volume Edit Handles, in this case nothing is displayed
2. Check if the Disable Handles option in the Element Selection tool is enable (image 2)
3. If it is, disable it and ensure the Element Selection tool Method is set to Individual and the Mode set to New
4. Click on the white rectangular section clip box and the blue and green Clip Volume Edit Handles should show (image 3)
