From the manual:

"   When a window is less than the full width, text lines too long to
fit are frequent.  Continuing all those lines might be confusing, so if
the variable `truncate-partial-width-windows' is non-`nil', that forces
truncation in all windows less than the full width of the screen,
independent of the buffer being displayed and its value for
`truncate-lines'.  *Note Line Truncation::. "

So try to put the following in your .emacs:

(setq truncate-partial-width-windows nil)

You can also have a look at the variable  truncate-lines
if you want to set this on a per-buffer basis.
