Try uninstalling Yahoo Messenger then downloading it again. You won't lose any of your contacts, I assure you:

Click on: Start

Click on: Control Panel

Click on: Add/Remove Programs

Click on: Yahoo Messenger then remove

Download Messenger from one of the following links:

For Mac:

http://messenger.yahoo.com/mac.php

For Windows Vista:

http://messenger.yahoo.com/download.php

The new version of Yahoo Messenger just released (9.0 Beta):

You may have too many programs running in the background draining your system's resources. Tuneup Utilities 2007 is an excellent program which has a Start-up Manager Tool which you can use to disable unnecessary programs from automatically starting up when you boot or restart your computer: http://www.download.com/3000-2094_4-1069...
