I have Mathematica 9.0.0.0 Student Edition.

When I enter an example from the docs (into a new notebook):

DSolve[{y''[x] + 3 y'[x] + 40 y[x] == 0, y[0] == 1, y'[0] == 1/3}, y,
x]

It comes up with

DSolve::deqn: Equation or list of equations expected instead of False in the first argument {40y(x)+3y'(x)+y''(x)==0,y(0)==1,False}. >>

Peculiarly enough, it seems to work if I hit shift-return in the example in the doc window.

Any ideas what I am doing wrong?
