Calypso 7.2 software with its SP updates is having problems calculating intersection and calculating kink point. It is also no longer possible to check the PCM functions within the element without the PCM license, as it was in previous versions. We updated Calypso from version 6.2 to 7.2 as we thought it would improve our measurement performance, with these errors we are sorry to have updated the software.

I believe that started around 7.0, maybe even 6.8.
