Hi Joshua,

well, it depends...

  When looking for an exact solution of a problem, Maximize might be part of the
steps taken by Mathematica. In this case, it would be annoying, because it would
take great effort to find out, where and - more important - why in the whole
process of (not) solving the problem the exact methods fail.

  If you want an approximation, use NMaximize. I use to type only the "N" followed
by Ctrl-L (on Windows and Linux - got no experience with Macs), when an exact
Funtion fails.

Cordially,
   Peter
