Selecting subentities with CTRL + Left Mouse

I have try the sample from Autocad ObjectARX 2007\samples\entity\subentity. If I run this sample in Autocad I could select subentities by holding the CTRL key and left clicking on the subentity when the subentity is hover. In Bricscad version 10.5 the entire entity is hover and not the subentities. Also in Autocad the functionsgetSubentPathsAtGsMarker getGsMarkersAtSubentPath

subentPtr

are called when hovering with the CTRL key hold down, but in Bricscad they are not called.

Is in Bricscad another way of selecting the subentities or I must do something else in code to be able to select the subentities by holding the CTRl key down when selecting?
