I can now reproduce this problem. Upon starting the program, if I wait for the health indicators to stop moving (i.e., arrive at their final positions) before starting Registry Cleaner, I'll get a Scan Report when Registry Cleaner completes its scan AND I'm able to correct all identified problems the first time. If I start Registry Cleaner before the health indicators have stopped moving, I will not get a Scan Report and Registry Cleaner rarely, if ever, repairs the identified problems the first time. Strange, but at least I know what NOT to do.
