Default entering to topics

Hi all,

We have just made an upgrade to 4.2 and the order of the posts have changed from reverse-chrono to chrono and now we see the oldest comments on Page #1 and the most recent comments on the last Page. Is there a way to change it when the users clicks on any topics it would automatically direct the user to the last page of the topic (i.e. to the most recent comments) and not the first one?

If that is not possible, is there a way to change the post ordering from reverse-chrono to chrono? 

Thanks in advance,

Ody
