Hi Vincent,
What exactly do you mean by "when I use the other way and call the
destructor (I clear the viewer map I get) there is a crash in", as
these seems odd, you never call the destructor, all you can do is call
delete, but in the case of the Viewer class you should never be
calling delete yourself, rather leave it to C++ to clean up in the
case of creating the Viewer in local scope on the stack, or using a
ref_ptr<> when you manage the Viewer on the heap.
