Hi J143,
Thank you for pointing this.

Hi ClevelandTech,
My Device is Cingular 8125 (HTC Wizard) Running Microsoft Windows
Mobile 5.0 OS 5.1.195(Build 14928.2.2.0). Cingular ROM Version
2.25.11.1 WWE Dated 05/11/06. ExtROM version 2.25.11.102. I did not
install other programs.

I checked it again. Contacts/Notes and Calender does not have a Menu-
>Cancel option. No File->Revert to Saved either.

Like Todd and Beverly mentioned, I can find "Menu->File->Revert to
Saved" item in Excel and Word.

Thank you all for your time and help.
Tom
