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.
I am working on a mosaic. My initial stack turned out ok. Â
After lpc, cbg, csc, I loaded the adjusted image. I have the DPP section on 15%, 3 sigma, 0.0% base.
When I select neutralize-BG the image goes pure white. I have attached two screenshots to illustrate before and after. Is there anything I can do to avoid this issue? Of course, I can not select the neutralize-BG and proceed. But I am curious to know if I have done something wrong to cause the white screen. Thanks.

I've seen that occasionally. Usually it seems to happen when there is an issue in the background itself, like when calibrating with darks/bias that have a problem in them or something like that.
