UnitStep problem

When I use the example

Table[UnitStep[x], {x, -3, 3}]

I get


and not

{0, 0, 0, 1, 1, 1, 1}

as the example in the online help suggests.  DiracDelta[1] yields 0,
i.e. UnitStep should be defined (this was just a test whether or not
the package is loaded).

What is the problem?

Please respond by email, as well.
