Installing 4.5.10 on Mac OS X 10.5.1
It installs fine and even opens the preferences for me. However, there's no Zimbra PrefPane.
I've checked using terminal and there IS file /Library/PreferencePanes/Zimbra.prefPane.
As myself, when I double click this file, again, it opens the Preferences, but there's no Zimbra PrefPane shown.
Am I unique in this experience? Any known solutions?
