[AUCTeX] RefTeX ToC, open files only in one frame

[Konstantinos Theofilis]

Hi,

Recently the RefTeX ToC behaviour I was used to, has changed.Let me try to 
explain:

I have a multi-file latex document. I open the ToC with C-c,=, and I get the 
ToC table on the left side of the document. When I go to a section in the ToC, 
and hit space or tab, i normally get the file in the main frame. But if I go to 
another section in the ToC, that corresponds to another file, it will open it 
*under* the previous file.

Here is a very crude representation:

|—————|———————————|
|                  |                                       |
|       Toc        |            File 1             |
|                  |___________________ |
|                  |            File 2             |    
|_ _______ |___________________|

Now, what I want is that when I have file 1 open, and go to a section in the 
ToC that is in another file, file 2, that file 2 should be in the place of 
File1, and the file 1should not have its own frame anymore.


This happens with Emacs 24.5 and auctex 11.88.6 in OS X and Emacs 24.4.1 and 
auctex 11.88.6 in Debian Jessie

Until recently, I was getting the behaviour I want now. However this changed in 
the past 2 months. I do not know if it is because of a change in auctex. Just 
for completeness, I must mention that I also have switched to a monitor with 
higher vertical resolution, if it has anything to do with it.

Any suggestions on how I could go back to the behaviour I had before, would be 
greatly appreciated.

Kind regards,
Kostas
