...Unless you did something like this, I can only assume that it's somehow now been made automatic when you download, or perhaps AHP reads the eeprom when it's started for comparison with what was most recently written. Do the dates and times on your ahpeeprom_w.txt and ahpeeprom_r.txt files agree with either of these suppositions?

I don't have the resources to do a before and after file compare but believe from the above that a read is not done at the time of a download. I'll keep an eye on the ahpeeprom_r.txt file to see if I can correlate any reads of the file.
If an .ahx file could be recreated from the ahpeeprom_r text or bin file, it could be a very powerful recovery/diagnostic tool.
