Hi Robert, I get it I think!
To solve the problem, I set my CommandManager ref_ptr as a private member in my class which launch the frame loop. That is to say the dragger->setCommandManager(...) method is not sufficient... and the commandManager instance is lost when leaving the block where is was created... In Dragger(.h), command Manager is set as a CommandManager* and not a ref_ptr !! This do not seems normal, isn't it ? in my code, a ref_ptr store the instance, and that's why, leaving the cration block, the ref_ptr delete the instance, because the dragger's command manager pointer do not increment reference count. (Don't know if I am understanable, but it looks a good explanation of the problem.) So now the last question is : is it normal the dragger do not store the commandManager in a ref_ptr ?
