Cart places order on wrong customers account?

Hi,

This has happened to me twice now...

A returning customer is checking out (customer 1)....at the same time another customer is creating an account but not placing an order (customer 2).

When the order is complete, the account name is customer #2, the bill to and ship to information is for customer #1 (the person who actually placed the order). The order history shows the order is placed by customer #2, the wrong person. Natural BOTH customers are disturbed by this.

Has anyone else experienced this problem? Any idea how to correct/avoid the problem?

Thanks in advance,

MaryM

I have heard of this problem, but only with people who are storing sessions in files and not in the database. Make sure that STORE_SESSIONS is 'mysql' in both of the configure.php files.
