How are message check boxes enabled with GroupWise 8 Support Pack 2

In GroupWise 7, each message in WebAccess is preceded by a checkbox.  These checkboxes were removed with the release of GroupWise 8.  Due to popular demand this feature has been put back in starting with GroupWise 8 Support Pack 2

The checkboxes are not enabled by default with the installation of Support Pack 2.  There is a new setting in the webacc.cfg file called List.Checkboxes.show.  This is set to "false" by default.  To re-enable the checkboxes, change this setting to"true" and restart Tomcat
