Hey, no reason to become evil
I checked the solutions, went thru most recommendations, however, no permissions where given, so I have to continue searching for a proper way to solve this problem for me. I am quite an experienced Apple user and I had some problems with permissions, which came from mac OS side. So I did not used the forum here jet. Also I worked many Jeans with Adobe progs. and I have to get used to the Affinity style, also in the form. Affinity progs are the best, that happened to me in the last year, as I am retired and cannot afford expensive Adobe progs anymore. So please understand, that I opened a new topic. By the way, these problems appeared only after I updated to Catalina, before no such problems were observed and I just enjoyed to work with Affinity programs.
Have a good time.
