After upgrade to v5, Parallels loads on Startup. How do I disable this?

I am running Parallels 5, with a XP virtual machine set up on my MacBook Pro.

Since upgrading to v5, I notice that Parallels service is loading on startup. I only noticed this because little snitch detected Parallels trying to upgrade on system startup. I only use parallels once a week when I need to run an app in Windows. I would rather not have Parallels start automatically and load it manually when I need to.

How do I prevent parallels from loading on system startup? Is this possible?

Thanks,
Rich
