OK,
JScript is NOT the same as JavaScript
JScript is Microsoft's version of Javascript

but does anyone know what the difference is?

I had I look at this page:

http://msdn.microsoft.com/scripting/

and found this in the JScript FAQ:

How do JScript and JavaScript compare?

JScript fully complies with ECMAScript. While JavaScript 1.1
and JScript 2.0 served as the basis for ECMA standards work,
the standards process has resulted in significant language
improvements in the areas of Unicode support, IEEE math
functions and improved date functions.
Well, that's cleared up that mis-understanding hasn't it??!!!
