IE11 and ToolBook

IE 11 has trouble displaying ToolBook web content because Microsoft changed the user agent string that the browser uses.
While SumTotal has released a patch to fix ToolBook content for ToolBook v11.5, they have not released the patch for any other version of ToolBook.
PLEASE note that the PowerPac fixes the IE 11 issue for all versions of ToolBook back to v8.9 (TB 2004). Furthermore, if your installation does not include the patch, then the PowerPac will patch your v11.5 content as well.
