Before my system crashed, when I typed a name in the To address field of a message, The Bat would fill it in with the correct name.  After the crash, I had to reinstall all my software.  Now, when I type in a name, The Bat shows a dropdown with every name that potentially matches what I typed.

For example, if I type "Bob", The Bat now shows me everything from my address book with "bob" in the person's name or the person's email address.

I can't seem to find the setting to make it work like it used to.  Can anyone help me?  I have a feeling I must be overlooking something obvious.
