How to remove line between products in "What's New," "Featured," "Recent Products"?

[fepb]

Hello,

I just installed the Recently Viewed Items sidebox, which I think is similarly coded as the What's New, Featured, Random and Specials sideboxes.

If I set it to display more than 1 item, there is a line between each item. I'd like to remove that if at all possible and would appreciate any help.

Here is what I mean:



I'd like the items to be displayed without the separating line. I've tried hacking some tpl and module files but can't figure it out.

Thanks in advance.
