Bob--Thanks for suggesting that I save the profile. I had no idea that I could, but --thanks to your hint--it was easy to figure out and I have done it now!!!

One comment -- my new Beelink i5 8th generation mini-computer has worked flawlessly under ACP all night long for two nights. But the purchase was scary, because the system arrived with no documentation for setup. Fortunately, the company provides instead a super competent IT professional from Uraguay who walked me through every step! What if I they had assigned me a less competent tech support?
One question: My new Beeklink provides 4k display support but only 10 bit color depth. Is 10 bit enough for ACP imaging acquisition but maybe not enough for good processing with PixInsight? Or is 10bit enough for everything since I am very much at the amateur level.
