Since reformatting my hard drive and reinstalling Office XP, the auto formatting has gone away when I input phone numbers on Contacts.  I used to only have to type in the 10 numbers (a/c & phone nubers) and once I clicked onto another field the phone number I had just input would be displayed with the correct formatting.  Now I have to do it manually.  Does anyone know how to fix it back to the other way?

As an example, I used to type 2814965000 and it would automatically format to (281) 496-5000.
