Hi Roger,
If I understand you correctly, you want to switch to Yahoo! Mail Classic from the new Yahoo Mail. To switch, you just have to click "Mail Classic" on the top left hand corner next to "What's New." Once you click on the link, you will see a dialogue box asking you to confirm that you want to switch back to Yahoo! Mail Classic.
To clarify, enabling your Yahoo! OpenID does not affect your Yahoo! Mail.

I want to go back to my original classic mail window not the open ID window. How do I go about doing this. I know I can't delete open ID but want to use my old window:
