I am having problems with the Product Categories Widget. The title is separate from the category list. I have been in contact with the wp e-commerce team and they had me go in and change the default.css which made it finally show background color and the borders (which before only the title had - the categories were on my body background).
Unfortunately though they still look like separate widgets - totally weird. Anyway I am still in touch with the e-commerce team - but I'm beginning to wonder if it is in my atahualpa settings.
My site is http://carneysitch2stitch.com/ would you guys take a look? I would greatly appreciate it - I'm going nuts...well I'm going more nuts

Thanks!
