Flyspell-mode breaks CUA mode

[LaserDoodads Info]

After starting Emacs with -Q I start flyspell-mode in the
*scratch* buffer.  I then paste some text into the buffer and
turn CUA mode on from the [options] menu.  If I try to select
text using shifted arrow keys the selection is erratic.  That is,
sometimes text will be selected and sometimes not.  Often text
that is selected becomes suddenly unselected between keystrokes.
