Calendar does not run past end of 2012
 

I run a forum about a vacation destination and my users like to post the dates they are visiting on the calendar.

I noticed today that the calendar does not run past the end of Dec 2012. There is no drop down box for 2013 onwards and also if you use what the url should be i.e.
http://www.myforum.com/forum/calenda...o=displaymonth
it just takes you to Dec 2012.

Is there going to be a fix, or is there something I can do myself to ensure calendar functionality past 2012?
