Lightning still operates, but I must manually enter a future date (for example, I must type in a day in December in order to schedule an event for that day; I should be able to click "next month" and select the day from the monthly view). Reproducible: Always Steps to Reproduce: 1. Click on "New Event" 2. Click on the Start Date or End Date menu 3. Click on the "One Month Forward" button or "One Month Backward" button. 4. Start/End Date menu closes. Actual Results: Start/End Date menu closes. Expected Results: Should be able to see future/previous month w/in monthly view.
