This is weird thing I just noticed - when using featured products on front page - I've got 4 - they show all 4 in a single line, with no arrows (since only 4 items, nothing to scroll). But if I login, the last item drops down to form a second row and the scroll arrows appear. If you hit the scroll arrow the page jumps to the top. I don't know if this is new or I just didn't notice before as I rarely login to my own site. I've customized this template so I suspect I mucked something up. Anything obvious?

I'm on zc 154, many mods; site is meafordwool dot com
