I am working on a large landscape project (5700 photos) and generated a medium quality dense cloud using version 1.4.0. Now that I have updated to 1.4.2 the same project not only crashes Photoscan but takes down my entire system with it. I am running Photoscan Pro on a MacPro with 1TB SSD, 32GB RAM and 2 AMD FirePro500 with 3GB each. While the RAM is a bit on the low side, this configuration has not let me down so far, so I suspect there is some sort of bug in the latest
update.
