...I do not know what, if any, changes or improvements have been made to the unit.
1. Is there any way you can find out? THAT would be very good information to have.
2. If there have been ANY changes to the design of the hardware, it would *really* be a good idea to change the model number, or at least add a revision number on the label.
3. Will there be ab update to AHP released in conjunction with the re-release of the CM15A? We haven't had an update since October of 2011.
There are a lot of bugs that are still in the software (check out the link to the Bug List here on the forums - in my signature), and it would be wonderful if you have a developer who can try and squash some of them (without introducing others, of course).
