My current version (Photo Mechanic Plus version 2025.10, build 8858) is experiencing lockups, where I have to force quit and then can not restart the program because it won't release its process, even if I do a kill -9 ID, forcing me to restart the Mac. It happens in multiple areas, mostly if I try to move around too quickly.
The most recent lockup was because of the Reveal In Collections window. If you try to close it too fast, it won't close, yet you can open up another one, which I shouldn't be able to do. Eventually, the cursor starts to spin and the program hangs.
