I am having a problem keeping items in any shopping carts on any site. I have cookies enabled and have tried clearing the cache and cookies. I can put items in, but they don't stay. Right after I have put something in, at the top it will say 0 items in cart. We think it's a windows setting which I must have changed by accident, because regardless of what browser I am using, and how I set the cookies in each one, no shopping carts hold items.

Does anyone have any ideas?

We solved it ourselves. It was a firewall thing. One of our sons, who is a software engineer, finally looked at the problem, and set it to accept more cookies than it was accepting. I'm glad I found this site though. I think it could be helpful in the future.
