Problem with iTunes keep restarting itself

[tosca925]

I have noticed lately that every time i use itunes, either to sync my ipod or just play some music, when i have finished and close it after 2 or 3 seconds it restarts itself. It can do this up to three or four times before it stays permanently closed.

 

If i try 'file>exit' or just click the X in the corner of the window it still does it. Does anyone know of a bug or similar?
