Hello all,

i like to know, if the CTRL button or the shift button pressed during the drag and drop process in the object manager for my ObjectData.
I receive the MSG_DRAGANDDROP message and check the flags in the DragAndDrop structure. But I get always the DRAGANDDROP_FLAG_MSGVALID flag and the msg pointer is NULL. So I can't read the BFM_INPUT_QUALIFIER from it.
Has someone an idea what's wrong??
