Well this gave me a chuckle this morning! It looks like the "Reliability analysis metrics calculation executable" isn't very reliable!
I'm not even entirely sure what it was doing, but it happened during a file copy. Yes -- I tried to copy a file on Vista. I know that's not recommended without SP1 installed, but I'm that crazy risky kind of guy! I think to measure problems like these someone needs to create a "Reliability analysis metrics calculation executable reliability analyzer application." Phew. That's hard to say!
