yes, same here
It's not possible to change quantity or remove an item.
Tried to install the latest k2store 2.3.1 on top of the shipped k2store version 2.0 but after that the "image show" in top header module from the start page doesn't work anymore (New k2store 2.3.1 comes with a system plugin I think that breaks that image show functionality).
So hoping for a fix here too from gavick team (best with latest k2store version... which doesn't break image show in top header module).
^^^update: looks ok in Firefox
- but have above mentioned problems in latest chrome stable browser.
- IE7 remove items works but change quantity ends up in a total price "$NaN"?!
