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.
V1.077
I had some success with following work flow and producing a final image. I then tried a second target, evrything flows well until the end when I try to use the tools. If I try to Calibrate Background or Remove Light Pollution it results in a white image. I've tried GL4 and OpenGL and get the same result. Not sure where I'm going wrong. Anyone have any idea? Thanks

If I may ask. How are you doing this. Are you starting in a corner first or doing the whole image at once?

I have the same problem also with the star color calibration tool. It works fine in 1.075.
Hi,
I may be wrong but looking at your second screen shot I see that you have the ST slider (on the right hand side) set at almost to zero.  I think you will start to see your image if you put this back to 0.00034 as per the previous screen-shot.
Flipping the DPP check-box off-on will achieve the same effect I think.

Did you try Mike's suggestion? It looks like either the histogram has an issue suddenly or you manually stretched it differently?
I'm having the same issue right now. It looks like the (B) and (ST) slider always resets itself to 0.000. Is there a way to prevent this from happening?Â
Hi,
I've never experienced this problem and I have used APP a good deal in the last 18months or so: whenever I have invoked any of the tools options the image has aways opened in the tool workspace with the same B, W, ST settings as those of the image in the main viewer, and ditto on return with the adjusted image.
I assume that if you adjust the B seeting the image does become visible and that the tool then works fine? If this is so then you can at least proceed with your adjustments, but I appreciate the annoyance.
It seems to me that if this problem happens regularly / always then probably there is an issue with your data and/or your hardware / software environment which will need to be investigated.
I haven't had this issue in the past year that I've used it either, until processing my M51 data, but yes, I was able to successfully process my image of M51 after readjusting B, W, and ST sliders.Â
It was pretty annoying to always adjust the sliders back, after waiting for it to load in the viewer.
It would be nice to find out the root cause of why it does that...
