[Mac-emacs-users] read-from-minibuffer loses point if same buffer open twice

[Steven T. <ste...@ma...>]

This could just be an emacs problem or a behavior change between emacs 
20 and 21.

I'm finding with 21.3.50 that if I have the same buffer open in two 
different windows, when I try a query-replace in the window I opened 
second, after it accepts the match-string, it immediately sends the 
point of the second window to the point of the first.  So, if I have the 
file "foo.txt" open in two windows in the same frame, the first one has 
the point half way down, the second one has it at the top.  In the 
second window I try to query replace and after I put in "baz" the point 
in the second window jumps down to the middle before it asks for the 
replace string.

I've traced the problem with the function (read-from-minibuffer) in 
minibuf.c.  It appears that when it reads the minibuffer input, it seems 
to forget which window was active.  It seems to happen under all sorts 
of other conditions.
Has anyone else run into this problem?
