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 have a new problem. Many of the processes are very slow now. No problem with star analysis, registration, normalization, etc., though. One example: when I'm finished with an image, I save it in FITS, TIFF, and JPEG formats. I hit save, and then it takes something like 2 minutes before the window opens for me to select file type. Another example: I adjust contrast and/or sharpness, and it takes minutes to complete the adjustment to the image. Another example: after calibrating star colors, I go to open the new image and it takes minutes just to open it. I recently increased the memory available for APP to 12gb in an attempt to improve this, but it did not help. I am using a nearly brand new Macbook pro with 2ghz quad core and 16gb ram. Any suggestions?
Mm, and did anything change in respect to the type of data that you have versus your previous experience? What APP version are you using?
@vincent-mod I'm using 1.083-beta 1. Nothing is different in the type of data from previous experience. I reinstalled APP and processed a couple more images and it behaved the same. The star analysis, registration, etc. seems normal. The problem is with the image window. For example, if I make an adjustment to the contrast, it takes about a minute to show the adjusted image. When I am completely finished and hit save, it takes 50 seconds for the window to pop up asking me what format to use. It's puzzling.
@vincent-modWorking on another image. I cropped it and hit crop ok. Then when I went to open the new cropped image, it took 1 minute 20 seconds to open it in the image viewer. This is really bad. I'm baffled.
Yes that is too slow indeed, so are you maybe processing it using an external disk by any chance?
I'm not using an external disk.
