How can we have two Ebusiness Center windows open at the same time in Telesales

 Hello,
I work for a company where multiple clients can call into our phone system at the same time.  When demand is high, an employee must work on two organizations at the same time.  Out of the box, Oracle does let us have two separate eBusiness screens open at the same time in the same session.  Other companies must also find this to be an issue.  Can anybody recommend a solution?

Thank you!
