Memory Leaks

Hi It seems my engine has a few memory leaks (15 to be precise) I have created an app with nothing going on other then creating a window and DirectX device then rendering nothing until the end. When I exit i get 15 DirectX warnings and a message box from ntdll.dll saying there has been some memory leaks. Okay so now ive installed purify and ive got the report back saying where the leaks are coming from. The problem is that i dont realy get which bit of my code evokes the problems if at all. Kernal32.dll and User32.dll are beyond my knowledge. Heres the report does anyone know how i can gleam some useful informiation from this?
