If I understand, Derek, you are proposing a change to GnuCash code to improve it's behavior.
Going back to the original question, which was about the confusing wording of the warning, if the code is changed, should there be warnings tailored to each of the three cases? Note: Case 1 might mean that some third party app such as a file editor may be mucking around. Is this true? Is it possible to test the PID to see if it is dead or alive?
