I'm setting up a new site and using MarketPress for the first time. I don't seem to be able to get category pages to work. When I click on a link to a category, I get a page that has a heading like "Product Category: Gift Baskets" but there is only one product listed. It also seems to be displaying in list view, even though I've selected grid view in my store settings. - Brian
