Apple has released Mac OS X 10.8.3. You try it first. I'm not going to try it first...
Apple says, "The OS X Mountain Lion v10.8.3 update is recommended for all OS X Mountain Lion users and includes new features and fixes."
Some of those include Boot Camp additions, a new version of Safari and fixes for Messages, Contacts, Slideshow and others.
Click the Apple Menu and choose Software Update to check for update via the Mac App Store (ugh). http://support.apple.com/kb/HT5612
