I’m using delphi Delphi 10.3 Version 26.0.36039.7899 and installed the KSVC 6.2.3 with the GetIt Package Manager.
I have placed a TRzCheckGroup on my form. The items are filled runtime.
If in code the items.clear is called, and one of the checkboxes is checked, I get aan acc violation.
Now I have a loop to deselect all items, and then clear works ok.
So now it works, but it’s not a neat solution….
