I downloaded and installed Zimbra Desktop. I am using it with Yahoo Mail and another mail server. Everything works great except for one thing. I imported contacts but they sometimes disappear from my address book. If I click on "contacts" or "emailed contacts" on the left side on my screen under local folders, I can't seem to get back to all of my contacts. I can't find any buttons that go back. I hope this is just me, missing something. Please help.
