Remarks

By default, the DN_MOUSEEVENT event is not sent to the dialog callback function. To enable/disable sending of this event, use the DM_SETMOUSEEVENTNOTIFY message.
Do not enable this event unless you really need it: mouse events are sent very frequently!
A plugin may modify the fields of the MOUSE_EVENT_RECORD structure passed to it.
By default the DN_MOUSEEVENT event is not sent for an open DI_COMBOBOX. Use the DM_SETCOMBOBOXEVENT message to enable the sending of DN_MOUSEEVENT events.
