Issue in calendar regarding Fix#74

I am trying to set startTimeOfDay property of ColumnView. I am using internet explorer 8. The property doesnt get set.
calendar = new Calendar({

                startTimeAttr: "begin",
                endTimeAttr: "end",

                cssClassFunc: function(item){
                return item.calendar;
                },
                   store: new Observable(new Memory({data: daatArray})),
                   dateInterval: "day",
                   style: "border:1px solid grey;position:relative;width:88%;height:88%",
                   columnViewProps:{minHours:0,maxHours:24}

            }, "day1");
calendar.columnView.set("startTimeOfDay", {hours:9, duration:1000});

I want the calendar to be defaulted to 8AM while it loads. It should have 12AM to 11.59PM, but while loading the scrollbar should be at 8AM.

Another issue with calendar week view and day view.

I have a calendar which have month view,week view and day view. When i try to scroll in week or day view, the scroll resets to the top. This happens when I scroll by dragging the scroll bar using mouse. But when i scroll using the scroll in mouse, this issue does not occur. Please provide your inputs on why this occurs.

Please advise on these issues.
