Hallo, since I have neither Windows 11 nor any current AutoCAD release for testing but I've found an interesting adn dev blog entry, which could maybe interesting for OpenDCL. Does it have any effect to the built-in BlockView control of OpenDCL?

With regards, Fred
Thanks Fred, I will look into it.
