I downloaded the trial and have used it for 2 days using Mac OS 10.14.8. It crashed and the moment I tried to reopen it, it crashed again. Uninstalled the application, downloaded it again, and so far it works.
It sounds like the PanoramaX.app file got corrupted somehow. Haven’t heard of that before, hopefully it won’t happen again.
Unfortunately Panorama X has crashed at least twice since my original post. I’m running Mac OS 10.14.6, so the system is up to date. However after the program crashed the first time it locked up, I repaired a volume error. Since then when Panorama X crashes, it can be reopened and the data appears to be intact.
I am going ahead and subscribe. Hopefully this will not be an on-going problem.
