Yeah, well I don't know. When I first started to use a computer years ago there wasn't very many people using computers and hardly any one actually owned a PC, as the world was being run mainly from mainframes and dumb terminals. I can remember when the general population thought of computers as extensional science similar to astrology.

Alot has changed over the years and things have in many ways become more complicated because of all the new functions, features and the addition of an OS with a GUI. It's possible when upgrading from older to newer versions of software to have compatibility problems related to the version of the OS your running.
