I have an eclipse juno release.
When I try to access the preferences (under Window - Preferences) then Android, the preference page displays the message "An error has occurred when creating this preference page."
I also get a 'Problem Occurred' dialogue displaying the following:-
Unable to create the selected preference page. An error occurred while automatically activating bundle com.android.idle.eclipse.adt (255).
I don't know what causes this problem!
