In response to Keith Slavin's frustration with Simplify, I've found that
Factor and Together are often more useful.

                     (k + -I w) x
                    E             (k + m + -I w)
Out[1]= -----------------------------------------------------
             (k + -I w) (-(1/2) + x)    (k + -I w) (1/2 + x)
           -E                          E
        2 (------------------------- + ---------------------)
                       2                         2

In[2]:= Together[%]

         k/2 + I/2 w
        E            (k + m + -I w)
Out[2]= ---------------------------
                  k    I w
                 E  - E
