Switch User

I had to request a computer using my computer account even though I didn't have a computer yet.  I did that first thing in the morning and waited all day.  Then I was told I had to reply to an email they sent about my new computer.  After I requested the computer, I had to confirm that I would receive the new computer even though I hadn't received the new computer yet.  So I went to my supervisor's computer and I had to switch users from his account to my account.  So I clicked Switch User and typed in my username and new password and then hit the button that said Switch User.  That brought me back to the logon in page.  So I typed in my username and password again and hit Switch User and it brought me back to the logon page.  I did that a number of times and then asked what I was doing wrong.  I tried to switch users again and was about to hit the button that said Switch User and my supervisor looking over my shoulder screamed NOOOO! Hit Return.  So I hit Return and I got into my account.  I guess when I hit Switch User after typing in my username and password, I was switching user out of my own account.  So I filled in the form to confirm that I would accept the computer and emailed it back but it was 3:30 in the afternoon by that time and I was told that everyone in the IT group had probably gone home and they would not see it until tomorrow.
