While I love ATX, it is not as robust in the diagnostics as other software packages. I don't know how long you have worked with ATX, but I learned a long time ago that it does not have many bugs, it does however have many ways for the operator to miss a check box, entry date, or question that needs to be entered to make the software calculate correctly. It is my opinion that this is the reason ATX users are better preparers than other software users - we have to be to make sure the answers the software spits out are correct. Just my humble opinion.
