I am testing KStars 3.6.5 and Indi 2.0.2 on my RPi4 4GB under the AstroArch 64-bit OS. KStars crashes whenever I try to add the real world parameters of an optical train. Each time I click on the Telescopes .... button, KStars crashes. The Indi Server is left running but cannot be selected to keep it running during the time-out, it is always shut down and a fresh one started up.
