Check buttons not animated on clicking calendar names.
Created attachment 335748 Calendar selection with no animation (video)
When The user clicks the calendar name (for selecting/deselecting) in 'Manage your calendars' menu, the check box doesn't get animated. When the click goes to the checkbox, the animation runs.
Please reassign if this is a gtk+ bug.
