I've stopped saying "It works for me," because if it worked for you, you wouldn't be complaining about it. It therefore behooves me to accept your statement at face value and see if we can determine why it is not working for you -- whether said failure is my fault or not. Maybe it's user error, maybe it's a bug. Either way, I should identify the cause of the problem.
