Edsel, did you know about Drake's enhancement where a right-click on many of the line items in a calculated return will bring up a box that shows the source entries that feed into that line? It's one of the tools that the support people use, and it was made available to the preparers.
I called a couple of times, mostly about state issues early on in the season where I alerted them to something that needed to be corrected.
Overall, from that survey it shows that Drake's customers are happier in almost all areas that any other software out there. Good for them.
