Multiple Logins Required

I am running Parallels 3.0 on a MacBook Pro. I have Windows installed via bootcamp. The Windows installation has an admin account and a user account.

When I startup Parallels I have to login twice using the Mac login window before Parallels really does anything. When I close down Windows I have to login again (using the Mac login window) before Parallels ends.

Any thoughts on why this is so, and if there is anything I can do to not have to do this

Thanks
