Oxymoron: Microsoft Intellitype

Ran into a problem with a Dell Latitude 830 when connected to an external projector: PowerPoint and other programs would zoom to 400% no matter what. When scaled back, they would zoom again. I found one reference to this strange behavior: http://www.experts-exchange.com/OS/Miscellaneous/Q_22099388.html Remove Intellitype and things were good again. It appears it only affects Latitude 800 series, but I can't be sure of that of course.
