Indeed.

Sure. `ispell-word' has a different behavior when a region is active.
,----[ C-h f ispell-word RET ]
| ispell-word is an interactive compiled Lisp function in `ispell.el'.
|
| It is bound to M-$, <menu-bar> <tools> <spell> <ispell-word>.
|
| (ispell-word &optional following quietly continue region)
|
| Check spelling of word under or before the cursor.
|
| [...]
|
| Interactively, in Transient Mark mode when the mark is active, call
| `ispell-region' to check the active region for spelling errors.

A quick grep through the emacs sources reveals, that at least those
modes make use of this new feature.

But reading the docs, you can put
(transient-mark-mode -1)
into your .emacs to turn it off, and only when you want to use the
special active region features, you turn it on for the following command
with `C-SPC C-SPC'. Then you have the coloring and special region
handling only when you really want it.
