After tracking down a "bug" in Ubercart, I thought I would share it with the community. I had a support email for someone not being able to add an item into a shopping cart that is powered by Ubercart. User was running IE7. For the life of me I could not get Ubercart not to dutifully add the item that was requested to be added to the cart. I started turning off functionality it IE (javascript, etc). I then stumbled upon cookies. Apparently, the user didn't have cookies enabled or a security setting barred cookie use.
