Posterior probabilities and utilities not shown

[Francisco Javier Díez]

If I compile this influence diagram, http://www.probmodelxml.org/networks/id/ID-decide-test.pgmx, add the finding "Result of test"=positive and remove it using the option "Remove finding" at the contextual menu, the probabilities and utilities are not updated. However, if I remove the finding by double-clicking on it, the problem does not appear.
