New Products no longer random

My new products for the month appear in a centre box on the front page. These used to appear in a random order, but now it doesn't seem to change any more.

How can I change it back to random?
I am using ZC 1.3.8

My website is http://www.mercuryrisingbooks.com

Hi,

Ousel:

My new products for the month appear in a centre box on the front page. These used to appear in a random order, but now it doesn't seem to change any more.
I can't reproduce the problem. Every time I refresh the front page of your site the order of the new products changes for me.

Regards,
Christian.

Hi Christian,

It seems to be working now. I noticed it because when I list a new product I go through this listing to check that additional images have uploaded correctly, and the list had not changed, even when the page was refreshed. Perhaps it was a glitch on my computer that has corrected itself.

Thanks for checking.

Hi, I have the same problem, but reversed. I want to display the new products on the home page not in random sort but the newest to oldest.

Can somebody help me?
