Sorry, Alan, but this Mail program seems even MORE BUGGY than I realized before....
A. Yes, when I create a NEW card in my Address Book with the "Test Company" and assign the email address the way you suggested, then YES, Mail would recognize that one address no problem.... But wait....
ONLY if I type the name as "test" it will catch it... If I type "Test" --- forget it.... So maybe Mail does not recognize the NAME of the company (which is saved as "Test"), only the email address (which is saved with a lower case "t")... That's not so good...
B. Going back to my already-saved company names, and making the change you suggested does NOT help... But...
C. But then when I type in an old name, it depends HOW I start typing it... If the name was saved starting with a capital letter, Mail wont catch it, but if I type it starting with a LOWER case, Mail will catch... So -- again -- you'd think that Mail recognizes only email addresses in your address book, not names of companies, right?
D. WRONG... I type in a name of a company, Mail does not catch. So I start typing in the EMAIL ADDRESS of that company, Mail STILL does not catch it.... -- And this is after I made the change per your suggestion...
MAYBE IT'S TIME TO MOVE ON WITH OUR LIVES, AND CHOSE ANOTHER MAIL PROGRAM? What do you say?
