Bichur, I downloaded, installed and then updated the version of SDC available for download at Stardock.com (per Tarkus comment in another thread) I now have build 86 and it seems to have fixed the problems I was having. Not sure why all previous updates stayed with build 85.
Currently on 2.07.332 build 86. Not showing the frameline problem like SNK, Jeff T and Thomassen - yet.
