Actually, your answer makes sense. The only behavior pattern that I could think of, was that the time cleaning up the profiles might have annoyed the system and it lost patience with me. I will modify to my technique. After I go into the compare mode, then I may see something that I want to fix and I go into the EDIT of the profile right there. Perhaps that triggers the timer. As a solution, I exit out of the merge event, do the fixing, and then go back into the merge function. I will post a followup message with the results. Thx!
