If any of you used to change the duration of the notification banners, the default method (hah, there's a pun there!) doesn't work any more.

Open terminal and try to increase the duration to 20 seconds:
defaults write com.apple.notificationcenterui bannerTime 20

Log out/reboot and check. No change! But don't worry, I'm here to help.

Edit the local plist and change the <string></string> tags around the "20" to <integer></integer>. Or, if you didn't bother to try with the "defaults write" method above simply add the two lines shown below.

After fixing, close to the bottom of ~/Library/Preferences/com.apple.notificationcenterui.plist is:

<key>bannerTime</key>
<integer>20</integer>
