I wrote here some time ago about a problem with the McAfee \ Outlook Toolbar add-in. The McAfee \ Outlook Toolbar would only appear after I clicked on (Outlook 2007) Tools \ Options or Tools \ Trust Center. As soon as I clicked on either Options or Trust Center the McAfee \ Outlook Toolbar add-in would magically appear.
I spent, literally, hours online with various McAfee techs as they controlled my computer.
Well, the latest Skype beta 4.1.0.130 seems to have solved the problem so I assume the problem was caused by the earlier beta version of Skype.
