I've just run into an issue where the checkbox does not appear on an AdvStringGrid when the application is compiled for a 64 bit platform and in release mode. When compiled in debug mode for the 64 bit platform it works as expected as well as for both modes (debug and release) when compiled for 32 bits. The checkbox is still there, the state changes when I click on the cell but I don't see anything on screen.
I'm using Delphi 10.4 and windows 10.
Regards,
Richard
