Help! Can ONLY log in as Administrator!

I have Windows XP installed as a Parallels virtual machine, with 2 user profiles: the obligatory Administrator, and a personal one.

I've set up the personal profile as the one I normally use, because this is the same as on my old Windows machine, making it easier to transfer settings. But every time I close or restart the VM, it logs in automatically as Administrator. Even though there are different passwords for the 2 profiles!

Has anyone else had this problem? Any idea of a solution??

(It doesn't matter whether the logon uses the Welcome screen or the old-fashioned dialog box; the result is the same. I have Windows XP Pro with SP3.)

Thanks for any help you can give!
