Mathematica3.0 question

Hi. I am evaluating the trial edition of Mathematica 3.0. I had
a question which is probably obvious but since I only have the online
help manuals I am having problems.

If I take the expression
InverseFourierTransform[Exp[-I d fx^2 Pi/(2 lambda)],fx,x]

Mathematica gives me a nice answer. However, it won't give me
an answer to
InverseFourierTransform[Exp[-I d Pi/lambda (1-fx^2/2)],fx,x]

no matter how I break up the exponent, into the constant term
and the variable term.

Sure, since one term is constant, I can omit it a priori, but there
must be a way for Mathematica to handle this properly?

btw, I'm trying to decide whether my company should buy MM 3.0, or
some other system, if anyone has any speed
comparisons for numerical manipulations or plotting between MM 3.0
and other systems for Windows or WinNT i'd be interested in seeing them.
(i know, different programs aren't designed for the same purposes.
but as long as the numeric computation speed hit isn't too great we'd
prefer the symbolic stuff of Mathematica. )

thanks
