[otrs] OTRS 2.4.1 Links in agent notifications are not clickable links

Greetings, I have OTRS 2.4.1 install and mostly configured with the exception of one issue. When a notification goes out to an agent user, such as that for a New Ticket, a Queue Change and the like, what should be a clickable link back to the system and ticket is displayed as plain text and NOT as a clickable link. For example: http://myserver.mydomain.myorg/otrs/index.pl?Action=AgentZoom&TicketID=xxx is NOT clickable. This works fine an older install (2.2.2) that is in production. I've compared the lines in the notification forms that specify this and they look identical: 2.2.2: :///index.pl?Action=AgentZoom&TicketID= 2.4.1L :///index.pl?Action=AgentZoom&TicketID= So my question is two-fold: 1: Is there a way to get this working correctly in 2.4.1? I see a bug issue for this when using Thunderbird as an email client, but we are using Outlook/OWA with Exchange 2003 on the backend. 2. If item one can not be done, what is the path to update from 2.4.1 to 2.4.2 while keeping the already established configurations of users, free text settings and such. This install is on Windows 2003 Server Std SP2, using IIS 6.0, ActivePerl 5.10.0.1005 and MS SQL 2005 for the database. Thanks
