Thank you, Ole! It worked like charm, which again proves the point that reading the docs isn't enough. You need hands-on experience. I was too dumb to put 2 and 2 together despite having read about the
@on_main_threaddecorator.
Your remark about redundant _objc_ptr was an eye-opener. I'm upset 'cause I spent quite some time to dig it out )))) Thanks again.
