"Tipped requires ExplorerCanvas (excanvas.js)" - error when logging in to Deltek Collaboration

Problem: I receive the "Tipped requires ExplorerCanvas (excanvas.js)" error message when logging in to Deltek Collaboration.

Cause: The Google Chrome Frame is installed on Internet Explorer 8 but not enabled.

Resolution: When you are in Internet Explorer, click "Tools" then "Manage Add-ons." On the left side of this page you will see "Show." Underneath that is a drop-down, click on it and select "All add-ons." Then scroll to check the Chrome Frame.  If set to "Disabled", right-click on it and choose "Enable."
