I write MFC application, but when i 开发者_Python百科launch it, in task manager on applications tab all applications list are disapear. if i do active some applications then she appears in applicion list, and when i close my MFC app all aplications are appears in app list on application tab. Why this happening?

My guess is that you are using Vista or Win 7, you are running your application as Administrator and task manager is NOT set to show all tasks from all users.
