The previous version of PicSure expires on 1 January 2018, and Version 188.8.131.52 will expire on 1 January 2019.
PicSure is a half-completed package, but I just do not find time to complete the functionality at this time. GEM4D is taking most of my time as the user-base increased significantly over the past year. Also, PicSure is sporadically required, whilst GEM4D is a tool that I use nearly every day.
Version 184.108.40.206 adds the ability to filter data within closed surfaces, even when these surfaces are closely spaced and sub-parallel. Other improvements are interface response and stability improvements.
