Issue Pinpoints crashes when selecting object properties of an Active Animation. Environment Continuum Pinpoint v1.93 Cause Image files used in the Active Animation do not exist or mapped through to the wrong path. Resolution Check that the Image Files used in your Active Animation are actually located at the path indicated. If the image files have been moved from the initial location used when creating the graphics then this could be the cause of the error. Copy the files back to the original location, now you should be able to edit the Active Animations and change the Image Files paths to the correct graphic location. This problem was found in Continuum v1.93 Pinpoint after an upgrade from an undetermined version and the cause able to be identified after importing those graphics into a v1.94 system. Presumably v1.94 does not have the same problem when attempting to view the Active Animation Image Files.
