I downloaded the updated patch version dated 10-11-2019 02:10AM. And it seems to be working. I've been using it for a few hours with no random core dumps. Won't be able to test the queue manager for a few days, though.

Let me add to this, I've been refining some scenes with Poser and it is coreing left and right. Don't upgrade to Catalina.

Well, after a few days on Catalina I would recommend against its installation. It is buggy. Not necessarily buggy with Poser, but with everything else. I now suspect the issue I am having with the Queue Manager is just a Catalina bug. I have a copy of Storyist that core-dumps with no apparent reason (I think it might be due to the auto-save). The developer said it was a Catalina bug and even tried to work around the bug, but no joy. There are lots of issues with iCloud, beyond repeatedly asking me to sign-in, options not working until I sign in (which I am), not unlocking with Apple Watch... then Apple forced me to reset my Apple ID Password this morning for no apparent reason and wouldn't recognize my new password on iCloud.com. IMHO, a very very bad reliability release for Apple.

I am on Poser 11.2.276 running Catalina. I have not been able to get the Queue Manager running correctly. I built a dual-CPU Windows box that I run renders on, and since I moved to Catalina it won't transmit images back correctly. I haven't been able to play with it to try and figure out what is wrong, as I am in the middle of a long run of renders. I am just executing renders manually on that machine for now. I suspect it may just be Catalina's new privacy for the disks. we will see.
