9 July 2020 - New and updated video tutorial using APP 1.081: Complete LRGB Tutorial of NGC292, The Small Magellanic Cloud by Christian Sasse (iTelescope.net) and Mabula Haverkamp
2019 September: Astro Pixel Processor and iTelescope.net celebrate a new Partnership! 
I tried creating a 2 panel mosaic with 370 images per panel (740 subs total). I loaded the subs from the 2 panels into 2 separate sessions. Sadly, when I try to do an integration with the setting "Per Session & All", APP integrates each separate session, but then crashes with the following message when starting the final mosaic integration. This happens repeatedly, so it is not a one time occurance. After I click Ok, the integration continues forever and remains in a stalled state as you can see in the second screenshot. I am unable to click "INTEGRATE" button again at this point and have to quit APP and start all over again from scratch. This is very infuriating as it takes several hours to get to that point. To experiment, I tried integrating "All" instead of "Per Session & All" and that seems to work.

Note that I have included 3 subs from each panel above, but in reality, I have 740 subs as described earlier.
Crash message:
Stuck State:
PS: I am running APP 1.077 on the latest Windows 10 (with all updates installed). This is running on a 64GB RAM system, with APP configured to make use of 60GB. The system has a 12 core AMD 3900X CPU & an NVIDIA 2080 Super graphics card.
I'm getting crashes, too, and my project isn't that complex - single stack with flats and bias.
I get no warning - the program simply vaporizes somewhere in stage 3. No message, no nothing, just poof and it's gone.
I had used 1.075 on trial and it worked.
No message, no nothing, just poof and it's gone.
So you mean it's a total crash, with APP quitting immediately?
APP integrates each separate session
Thanks for notifying us about this. So the integrations on the separate sessions do work fine right? Do you have the 2 final integrations at that link, that would be nice to see if I get the same issue.

Thanks for the reply. I added the integrated images (2 separate panels of the mosaic) to the original Google Drive link: https://drive.google.com/drive/folders/1YPJoxz6YU0XroowGeMwEfqdsv8KrZfBN?usp=sharing
