That seems OK. Do you happen to double-click on the date?
As reported by another user this causes that same error. It seems to make sense. The GUI have time to generate two click events, the first click destroys the control and for the second there are no control to destroy.
Maybe it is something with mattricks locale support (english is good, polish(other languages?) is bad).
Maybe, but I would expect problems with drawing (which seems good) rather than interacting.
