Hello Bryntum Team,

I found an Error in the Calendar Year View. When you click on a Day
with Events normally a little Window with the Events opens.

When you have an Event on the last Colum from a Month (see attached Picture)
and you click on the Day nothing happens when there is an Event.

If there is no Event the Dayview opens correctly.

It's reproducible in your Online Examples, for Example the Print demo:

Just add under modes the marked Code and some Events int the marked Fields
and try it out.

Greetings, Bastian
