Source specials in Emacs 22 /AucTeX and Miktex 2.6

Source specials in Emacs 22 /AucTeX and Miktex 2.6

[R McDonald]

I have virtually identical installations of MikTeX 2.6 and Emacs 22 on 
two machines, both running XP SP2. Both have the same .emacs file. The 
Emacs version is pre-compiled (5/20/07) from

http://www.gnu.org/software/auctex/download-for-windows.html

When I compile and then view a latex file on Machine A, using Yap, there 
are source specials. Every time I do an inverse search on this machine, 
there is a new invocation of emacsclientw. So after 5 searches, I have 5 
copies of emacsclientw running.

On machine B, Yap says there are no source specials, although C-h v says 
that the value of TeX-source-specials-mode is t. In both cases I am 
invoking the latex compiler and viewer via repeated invocations of C-c C-c.

The strangest thing to me is the different behavior on the two machines. 
At this point I would just love some suggestions for debugging this 
problem. Thanks in advance!

Check to make sure default.el and site-start.el are the same on both
machines, too (use M-x find-library, and leave off the .el just in
case).

Thank you, that was helpful. I did find a version of site-start that I 
wasn't aware was there. Removing it still left me with different 
behavior on the two machines, but it did eliminate one variable.

What finally helped (in case anyone else has a similar issue): I have 
set yap (the MikTeX viewer) to use emacsclientw with arguments "+%l %f 
-n". I wasn't using -n before. As far as I can tell, -n (which means 
"no-wait") invokes emacsclient and then shuts it down (it never appears 
in the task list). Forward and inverse search now work as they should.

There is still one behavioral difference between the two machines that 
is perhaps only a curiousity, but I wonder why it happens. When I 
perform an inverse search on one machine, there is no message in the 
emacs minibuffer window. Whe I perform an inverse search on the other 
machine, using the identical file, the message "foo.tex and foo.tex are 
the same file" appears. I'm not sure what process is producing the 
message or why it occurs on one machine and not the other. If anyone has 
thoughts about that, I would be curious. But the main problem was solved 
by using the -n option.
