On the events screen, the Arrears tab shows a list of tenants who ahve an arrears balance.

This screen also allows you to select a tenant by clicking on the tenants name.  A problem arises when you have 2 or more tenants with the same name, which doesn't happen often, but it could happen.  The problem is that the system might select the wrong one of those 2 tenants.  In the next version it will be able to differentiate between the tenants even if they have the same name.
