I'm pleased that this "legacy product" is receiving attention and support replies. I think that I and obviously others don't think it is really a 'legacy' product - it still continues to work and work very well. The fact that it has not received updates in 10 years means that - in general - it doesn't need them!!!!
I too am unhappy that the developer has not taken the effort to update the 'lookup' feature. Albeit not being a programmer, I would hazard a guess that this is a program much simpler than more recent ones and that it would not in fact take that much of a programmers time to update the lookup features to the new algorithms, whatever they are.
I think that "we are turning our attention elsewhere" is a cop-out, and that an honorable company would in fact take that relatively small effort! I'm a doctor, and I don't say - "Well, I decided not to update my knowledge on your disease because it's an old disease..." Lets take the high road....
