/*
These functions are required because safari 1.3 is broken - once users upgrade much better methods could be employed
Orignally most of the functions below where carried out via an elegant CSS Class structure. Once users stop using old
Safari's then switch back to this CSS method as it would be far easier to maintain. FYI - IE6 also struggles when inherited classed are
use with input fields.
