In 32-bit mode SET ENTERABLE and OBJECT SET ENTERABLE only set the enterable flag, not the visibility flag. In 64-bit, OBJECT SET ENTERABLE and OBJECT SET VISIBLE work as expected for objects on a form. The problem is the behavior specific to 64-bit mode in a list subform when setting object enterability during On Display Detail. In these specific conditions, OBJECT SET ENTERABLE(field;false) makes some objects invisible and enterable. > Also, 4D no longer draws pixels to create a bitmap of a list form, but rather, > requests Cocoa to update sub views of the window view hierarchy, > and lets the framework do its own optimisation to create the final result. I guess this is why OBJECT SET ENTERABLE now behaves erratically in a list subform. This is the only place in this structure where this functionality was used, so I guess it will be out with the subform and in with a listbox.
