So you want to clear the Contact Search Bar? No problem. You'll need to remove the Yahoo! Messenger cache directory. This won't affect Yahoo! Messenger directly, other than clearing local preferences in Yahoo! Messenger (this does not affect your Contact List, Archived Messages, or Voicemail messages).

Here's how to remove the Yahoo! Messenger cache directory:

1. Completely exit Yahoo! Messenger.
2. On your Windows desktop, double-click My Computer.
3. Double-click Local Disk (C:).
4. Double-click Program Files.
5. Double-click Yahoo!.
6. Double-click Messenger.
7. Right-click Cache.
8. Press the "Delete" key on your keyboard.

The "Cache" folder will be recreated the next time you open Yahoo! Messenger. Please make sure you check your preferences to make sure nothing has changed after performing the steps above.

Cache removed!
