We are currently evaluation Daypilot Pro and hit a major problem. I have two separate pages - one timeline and one month calendar, and the problem exists on both places.
I have buttons for paging to next/previous month. Paging forward, to next month/year, works perfectly. Paging backwards to previous month also works, until you try to page back to a previous year (ie. from January 2015 to December 2014). Then the browser hangs completely. In debug, I see that the scheduler says "Invalid date" and gets 'value: "NaN-NaN-NaNTNaN:NaN:NaN"'.
This is real dealbreaker. Can someone help us?
