Remember to cover the basics.  Including a minimal LaTeX example
file exhibiting the problem might help.

--text follows this line--

You may see the problem in the attached pictures. Suppose I use the
preview-latex mode and try to edit a formula.

I use the toggle option of [mouse-3] and view the original LaTeX
_expression_. See Prv_no_HiLt.jpg.

Then I try to select an element with the mouse or keyboard. The active
region may be either wider than the previewed _expression_ or be a part of
it. Independently of the choice there is no highlighting of the
previewed region:

a) If the region is wider than the preview I get Prv_HiLt.jpg;

b) If I select a part of the previewed formula the view in
Prv_no_HiLt.jpg. does not change.

Nevertheless I'm able to copy, kill etc. the active region. I did not
have the problem in older versions of Emacs and Auctex. Moreover I could
not solve myself when I tried to change AucTeX and Preview-LaTeX
options.

Information on Emacs and AucTeX highlighting on the Net is rather
scarce.

Help!

Thank you in advance, AA.
