Hi, can anyone comment on the relative stability of SW 2015 & 2016? 2014 was reasonably good, but we just switched to 2015 SP4 and it is not the greatest. My machine is locking up around 3 times a day and the other engineers are having the same problem. We work a lot with weldments which is something that SW always seems to struggle with. Does anyone know if 2016 is any better? Perhaps upgrading is the solution.
