UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Â Before I release it, I will make sure that everything is working properly and then I will release it.
If I start an integration from scratch, it will begin calibration. If I click the Cancel button, APP will just hang there and do nothing. The only way to clear this is to exit and restart the application.
As it happens I did this as well last night and APP actually stopped calibration but continued with the next step (star analysis? I'm writing this off the top of my head). Canceling again made APP stop. It did not hang. This was on the latest version of Intel macOS.
@wvreeven In my case the app wasn't hung at the OS application layer, but none of the buttons in APP were available to press, except for cancel after clicking it. In the Load tab for example none of the buttons were pressable but APP was still active and responsive.
The same happened to me. I run the latest beta (29) on Windows 11. I canceled almost immediately after starting a multisession process. The program doesn't use resources and seems not to be doing anything but all the buttons are grayed out except the cancel button (and the license and cfg buttons). So I have to close the window and start from scratch. If there was an option to save setup it could have saved me about 15 minutes of my time.
