Re: Flyspell-mode breaks CUA mode

[Richard M. Stallman]

    Why is it setting deactivate-mark?  I thought that was only set by the
    sort of interactive command that shouldn't be used in hooks etc.,
    which makes this problem sound more like a simple bug rather than a
    design problem....

Any change to the buffer sets deactivate-mark.  So flyspell's
post-command-hook should bind deactivate-mark to prevent that.

Does this fix it?
