A service pack is not an upgrade, mostly a service pack consists of bug fixes. Service packs should always be installed right away.

Software developers don't write perfect software and even if they did, problems arise in the future due to circumstances beyond the developer's control.

Also, service packs don't produce any revenue to Softrak, and I'm sure they would be very happy if they never have to issue one. So of course they wouldn't pre-program their software to have bugs.
