So doing some dragging and dropping and all is well except when ran as administrator, have unblocked WM_DROPFILES, WM_COPYDATA and WM_COPYGLOBALDATA via ChangeWindowMessageFilter/Ex and that does enable DragQueryFile so I can get the file paths but DragQueryPoint always returns 0 when without administrator rights it works just fine so is there other messages to unblock to enable the POINT structure to get filed in properly when elevated?
