Sherlock crashes when I try to open it. I may try 2 or 3 times and then it opens OR it may open on the first try (becoming more unlikely) OR I may simply give up and move on. I am using OS X 10.4.2 on a G5 2gig dual processor computer. Sherlock is 3.6.1. I have run DiskWarrior and everything seems to be fine. Consider me a NON-Techie, my computer training was in 1963-4 but haven't used it much since. Thank you, David
