--- Comment #4 from Dr. Ing. Dieter Jurzitza dieter.jurzitza@t-online.de --- I overread your hint - thank you very much, this is actually working - and moreover this helps me a lot. However, as I said, there are no comparable restrictions in windows, therefore I consider this a wine bug.
By the way, I had never said I wanted to copy schematics between different instances of ltspice, in contrast, I explicitly referenced to copying from within a single instance in my initial report.
Anyway, this is a bug - be it small or not - that I think would be worth fixing, as nobody expects such a behaviour.
Thanks again, take care
Dieter Jurzitza
