I don't know where you responded at.  Based on your response here and the instructions I have seen you give on your products I am seeing a pattern of communication which is sub optimal.  You seem to assume people know everything you know and therefore leave important details out of your communications.  This has a negative impact on the effectiveness of your communications.

For example your reply: "Hi, thanks for the report! Just responded to your other comment about this."

How much harder would it have been to say: Hi, thanks for the report! Just responded to your other comment about this on (place where you left the comment goes here).
