TM1Web Widget and Multiple Sessions


I’m using tm1-web widgets to display cube views in a dashboards. I’ve noticed that a new logon occurs every time I click on a dashboard that contains a view, even if I’m just switching between two dashboards (with a cube view) I get logged on again each time I switch and there are then many sessions against my user name. The sessions still exist (showing in Pulse) after I’ve closed down my browser.

Is there any way to prevent this?
