There are some double lines between the groups in the ScheduleView. Also, the lines of the headers in the MonthView are displaced.
When displaying week view as the first active view, the current day is highlighted properly. But after changing the visible range (left, or right) and going back to the week that contains today, the current day is no longer highlighted.
Also there are some borders (right ) missing from GroupHeaders (GroupHeaderButton that displays the day number) in MonthView , but only for the last day of each row in the week/displayed time range. See: http://demos.telerik.com/silverlight/#ScheduleView
