Why do you need to handle mouse clicks over a group box? Actually the group box is a special type of controls which is transparent for messages. Their window procedure returns HTTRANSPARENT when receives a WM_NCHITTEST message so any other messages are not processed by the group box. You can try to create your own CExtGroupBox-derived class and in the overridden WindowProc method manually handle the WM_NCHITTEST and WM_GETDLGCODE messages in order to allow message handling.
