How do I change the admin name in the popup dialog

Question

I am giving my old MacBook (10.6.8) to my mother and for certain reasons I didn't want to wipe it clean but just clear out some of my stuff and transfer it to her.  Everything has been successful, including changing the User directory name from mine to hers.  There is only one place that my name is still appearing:  When a change to a system setting requires a password, the password dialog box pops up with my name in it requesting my password.  If I type my password, it doesn't accept it, but if I change the name in the username box to my mother's name and put in her password, it works fine.  In other words, she is indeed the administrator now, but the dialog box still pops up with my name set.  This is a bit annoying and I would like to fix it for her, but I haven't found any ideas online.  Can someone help?  Thank you!

There is really only one good way to do this type of transfer: What to do before selling or giving away your Mac. If you aren't willing to do this, then you needed to make a new user account with admin status that would belong to your mother. Log into that new account and delete your old account. I suggest at this point you do that.
