Hi,

I've now had a chance to play with Windows emacs, and, with this feature
enabled, it works very nicely with JAWS (a popular screen reader).
However, if it's supposed to be autodetecting screen readers, this isn't
working at all: I had to add (setq w32-use-visible-system-caret t) to my
.emacs.

Although I don't really use it any more, I have a version of Window-Eyes
(another popular screen reader) from a couple of years ago (as opposed to
my version of JAWS, which is up to date).  Emacs wasn't able to autodetect
this, either.

I hope it might be possible to fix this before it's released...

Cheers,

Nikhil.
